Hello,
I am a "cancer" person and, in an effort to infer protein function(s) I have BLASTED a human male germ cell-specific mRNA and protein, which is encoded in human Xq28 and expressed only in testis spermatogonial stem cells, against the Dmel cDNA dbase to identify orthologues. I have done this using an E value of 10 or 1 and I retrieve 4 hits in the Dmel X and 2L chromsoomes. The identity is ~62% but in alow complexity region in the N-terminus. The stringency was high in order to get distant relatives. The proteins align between 52-56% in the same regions. What is your advise?
Note that there are no mouse counterparts to my protein and the human genome contains paralogs.
Thanks for any help on how to proceed.
Nick
