Hi everyone, I posted this a week or so ago, but got very few responses and
no postings-help! someone must have some idea! any ramblings will be
>I was wondering if any has hear of a higher eukaryotic gene organization such
>as this :
>2 genes, intronless, facing towards eachother (promotion-wise) that are
>absolutly critical for the function of a system. these genes show no homology
>to eachother (or anyother genes for that matter) but are conserved for over 500
>million years of evolution. they are absolutly critical for function.
>these are the recombinase activating genes. they are essential for immune
>system function-t and b cell rearrangement. a possible theory is that they are
>the resylt of horizontal gene transfer from a viral infection (intronless, 2
>genes for one function right next to each other on the same chromasome...ect)
>500 million years ago or so. they are almost completly conserved over this
>question: can anyone support the viral introduction theory?
> can anyone give me an example of any other system where 2 genes like
>this are essential for function, may have similar function (well maybe not
>similar but complimentary) and or are anything like this?
>i am really looking for any similarities anyone can propose, so ANY crazed
>sp[eculation is welcome!
>if anyone has an idea, but needs more info just email me,
