Gene or accession: LD22117 Release: 2 cDNA or EST error Comments: In AE003451, nucleotides 34'106-34'699 contains an ORF which is 98% homologous with Ras small GTPases such as CG2532 gene. No gene is currently identified at this site, just 3' of LD22117 (CG1619). It is possible that this new Ras small GTPase gene should be merged with LD22117. this gene should be on the plus strand, between the annotated genes spri and BcDNA:LD22117 . Evidence for the presence of a strong homology between this new gene and genes now known as CG2532, CG9807 and CG2885 (all encoding small GTPases) was reported in Hutter and Karch (Experientia 50:749-762 , 1994). I should stress that this sequence is also present near the CG2111 gene, again where no Ras small GTPase gene is identified yet. Pierre Hutter Subject: cDNA Small Rab GTPase gene in AE003451 (nt 106042-106636) Dear Gillian, Dear Sima, Just one more thing. In my first e-mail about the new small GTPase gene between the annotated genes spri and BcDNA:LD22117 , I had mentioned another nearby site which harbours an unidentified small Rab GTPase gene between CG9806 and CG2111 (on AE003451 scaffold as well). I cannot work out its genomic structure but when the AE003451 scaffold will be reannotated, nt 106042-106636 (referring to release 2.0) should definitely also be investigated for homologies to other Ras GTPases, EST sequences etc. ..
