READ AGAIN! It plays a role in IFN-gamma mediated autophagy. Without it, autophagy induction through IFN-gamma is abrogated.
FFS, now you are just quote mining! It is clearly not redundant or less crucial, as explained and evidenced by the association of disease caused by dysregulation of the gene.
Still, Eichler and his colleagues cautioned, there is at least one alternative explanation for their data: it's possible that IRGM is actually non-functional in humans and great apes, just as it is monkeys. They argued that this explanation is unlikely, though, since a deletion upstream of IRGM has been linked to Crohn's disease.
In addition, Eichler said, some orangutans carry a copy of the dead gene while others carry a copy of the functional gene suggesting IRGM has "'one foot in the grave and one out"' in that species, which sits at the first branching point in the great ape lineage. Even so, while Eichler said he is about 90 percent convinced that their resurrected gene theory is correct, he'd like to see more experiments done to assess IRGM's function in humans.
If the resurrected gene notion is right, Eichler said, it raises a host of questions about IRGM. For instance, since IRGM appears to play a critical role in bacterial immunity in mice, it's unclear what led to this gene's obsolescence in the monkey-ape ancestor. And more research is needed to address whether the revitalized form of the gene has the same function as its predecessor or whether it now has additional roles.
For his part, Eichler believes the locus is probably still involved in immunity and possibly auto-immunity. He speculated that another immune mechanism may have evolved around the same time that IRGM became a pseudogene, making it redundant and less crucial.
Either way, Eichler said, it's clear that the genome is a dynamic and plastic place. His advice: don't count a gene out until it's completely gone.
ROFL, actually you were by misrepresenting them. Your summary was woefully inaccurate and misrepresented what they said (or did not). Glad you apologized for it.
FFS, now you are just quote mining!
She is flat out wrong.
They are not wrong,
I'm deferring to ERV's Opinion:
ERV:
No yay! Cause IRGM isnt the same IRGM that we had 50 million years ago. Its now got an ERV LTR for a promoter, it sits in a different part of the genome, and its surrounding genome landscape has changed dramatically-- 33 retrotransposons (LINES/SINES/LTRs) have taken up residence upstream of IRGM!! Some people have a 20,000 base-pair deletion upstream from IRGM. This leads to expression of IRGM in wrong tissues at wrong levels, which could be a potential cause of Crohns disease
She is flat out wrong. IRGM is an important regulator of autophagy and disregulation of this gene is speculated to be associated with Crohn's disease. SNPs and deletions upstream of this gene (near the transcription site) are associated with Crohn's disease. Read for yourself.
McCarroll, S. A. et al. Deletion polymorphism upstream of IRGM associated with altered IRGM expression and Crohn's disease. Nature Genet. 40: 1107-1112, 2008.
Perhaps you didn't read their analysis?
Perhaps you are just unaware of the difference between the structure of a gene and the structure of the protein after processing. Perhaps you don't know the difference between an intron and an exon and alternative splicing. The structure of the gene changed, yes. Heck, the ERV9 insertion coincides with the transcription start signal. However after RNA splicing, the protein pretty much does what the IRGM protein does in mice. And dysfunctional IRGM genes (NOT PROTEINS) are associated with Crohn's disease. Got it?
But the copying mechanisms didn't keep the genes intact. Ed Yong again:
The part of the gene coding for the protein was kept in tact. The transcription site was the part that was affected.
It perfectly demonstrates why FLE is nonsense. A random event restoring a gene to functionality that may actually do more harm than good.
The gene works fine. Dysfunctional IRGM genes are associated with Crohn's disease. From a FLE perspective, it makes sense that old genes can become functional again (junk DNA is an argument from ignorance) due to the inherent optimal properties of the genetic code, the robustness of mutation induction and subsequent repair and viewing retroviral elements as vectors of optimization.
You, of course, would NEVER do that!!! Mu ha ha ha mu ha ha ha!
Difficult stuff, this "right" and "wrong" stuff, in the TelePhronetic world. Sometimes we have things that are right, but, no, maybe they are actually wrong, no, can't be sure, yes, they are right. Sometimes we have things that are wrong, but, no, maybe they are actually right, no, can't be sure, yes, they are wrong. In fact, "right" and "wrong" are synonyms and can mean "right" or "wrong" - it just depends on how the debate is going!
Mu ha ha ha mu ha ha ha!

Note how phrony tactics evolve.
1. Phrony introduces new item for discussion, with hidden creationist agenda.
2. Prhony's response to follow up questions clearly demonstate that prhony hasn't actually comprehended the articles.
3. Prhony attempts to overwhelm the users of an IT forum with technical jargon related to genetics.
4. Subsequent material (sans technical jargon) adequately answers the questions posed.
5. Prhony denies, reintroduces technical Jargon, and Strawman/Red Herrings (JunkDNA)
6. Prhony is proven wrong (not once, but repeatedly)
7. Prhony denies, and attempts to shift blame on my summary which appeared after the quotation which he so vehemently denied (and was proven wrong), also maintains strawman, and further technical jargon.
8. It's pointed out that Technical Jargon appears to be inapplicable to humans (supported by linked quotations).
9 Phrony denies and accuses me of quotemining.
Anybody care to add or amend my analysis? (Not you Prhony)
Quantum Wrongness?
You've left out the usual petulance, insults and ad hominems, and the repetition of the same posted quotes over and over and over.... ad nauseam. But otherwise - pretty well spot on.

Brilliantly put! Quantum indeterminacy - it can be right or wrong depending on your measurement LOL!
Or was it Brownian motion....????

Can you read? In HUMAS TOO!!In mice.
Well, after reading your OBVIUOS misrepresentation, she would have been wrong. After re-reading what she actually said, I was wrong in saying she is wrong. You however still misrepresented what she said, and it probably because she did not give all the necessary information for you not to misrepresent her. Mamma ERV is not going to be happy with you. Next time rather ask mamma ERV to explain these type of things to youYou said Abby was wrong (She is flat out wrong.)
I was wrong in saying she was wrong. However she did not give all the information which lead to you misrepresenting her. At least you apologized for this.Were you lying, or were you wrong, or both?
Right.... so discussing evolution and genetics is a creationist agenda? O righty then...1. Phrony introduces new item for discussion, with hidden creationist agenda.
ROFL, you still don't how IRGM works in humans? I think you should rather not say "other" people don't understand articles. Standard trash talk of course.2. Prhony's response to follow up questions clearly demonstate that prhony hasn't actually comprehended the articles.
you seem to be the only person that is overwhelmed by simple genetics.3. Prhony attempts to overwhelm the users of an IT forum with technical jargon related to genetics.
Ruueally. If you don't even understand the "technical jargon", how would you know?4. Subsequent material (sans technical jargon) adequately answers the questions posed.
Ugh5. Prhony denies, reintroduces technical Jargon, and Strawman/Red Herrings (JunkDNA)
Wrong in saying ERV is wrong. Right about the function of IRGM in HUMANS. Right that ERV did not present the necessary facts for you not to misrepresent her.6. Prhony is proven wrong (not once, but repeatedly)
ROFL, and still you don't get how IRGM applies to HUMANS.7. Prhony denies, and attempts to shift blame on my summary which appeared after the quotation which he so vehemently denied (and was proven wrong), also maintains strawman, and further technical jargon.
8. It's pointed out that Technical Jargon appears to be inapplicable to humans (supported by linked quotations).

Got any more article written by others you wish to misrepresent? i was wrong in saying mamma ERV is wrong (my apologies), right in saying you misrepresented her, and you did the right thing.
Could you send the message to mamma ERV to give a little more information next time so you don't misrpresent her?
If anything? Uncertain?
Let's go over this SLOOOWLY for you so that you can actually UNDERSTAND what it does.
...re-activation of an old gene that plays a crucial role in immunity...
"Immunity-related p47 guanosine triphosphatases (IRG) play a role in defense against intracellular pathogens. We found that the murine Irgm1 (LRG-47) guanosine triphosphatase induced autophagy and generated large autolysosomal organelles as a mechanism for the elimination of intracellular Mycobacterium tuberculosis. We also identified a function for a human IRG protein in the control of intracellular pathogens and report that the human Irgm1 ortholog, IRGM, plays a role in autophagy and in the reduction of intracellular bacillary load."
"There are two possible interpretations of our results. First, the IRGM gene is not functional in humans having lost its role in intracellular parasite resistance ~40 million years ago when the gene family experienced a contraction from a set of three tandem genes to a sole, unique member whose ORF was disrupted by an AluSc repeat in the anthropoid primate ancestor. In light of the detailed functional studies [11]* and the recent associations of this gene with Crohn's disease [6],[7], we feel that this interpretation is unlikely.
Prhony attempts to overwhelm the users of an IT forum with technical jargon related to genetics.
Yay, another philosophical argument from ignorance in the science section. That all you have?There is no empirical evidence for a creator or any God in any science we have covered so far in our short existence as a species. (an anomalous species?)
Another one of those who do not like biomolecular machinesI formally protest this thread and the Bio Molecular Machine thread as not worthy of a science sub forum.
You have the function, you have read about, you know what it does, you know that dysregulation of the gene is associated with Crohn's disease, and you want to argue it is not crucial? Why don't you go to a lab and ask them to silence or delete the gene so that you can understand how crucial the gene is in immune-related autophagic processesYour assertion that this abreviated hybrid gene is "crucial" for the human immune system.
Singh et al said in 2006:
"Plays a roll" <> "Crucial"
The more recent study refers to the Singh paper:
[/i]
*Singh SB, Davis AS, Taylor GA, Deretic V (2006) Human IRGM induces autophagy to eliminate intracellular mycobacteria. Science 313: 1438–1441.
Note they don't say the detailed functional studies found Crucial function. But then Singh et al didn't actually make the claim.
Looks like Mr. Censor is getting hyperactive here on this thread.
The screeds of jargon are thrilling I am sure, but just tell me this - did Jesus stuff it up via a retrovirus on purpose, and then resurrect it, Lazarus-wise, in a different position and somewhat chopped, on purpose, or is all this just the usual randomness of natural biology?
Can we debate the principles, and not quibble about the detail please.
Please elaborate on this. I think you have problems with the formal fallacy we call argument from ignorance.yay, another philosophical argument from ignorance in the science section. That all you have?
I have no problem with bio molecular machines. I have a problem with your using of the terms and your sly and sickening way of promoting your beliefs.Another one of those who do not like biomolecular machines. Hilarious that the protestations come from a certain demographic. You guys seem to hate to learn about biomolecular machines and how they control just about every aspect of your being.
Talk about cognitive dissonance ROFL.
