Subject: ADRC-035 Dear Clive, We are currently curating the abstracts for the upcoming Bellevue (Seattle) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstract: 'The Drosophila homologue of the human tumour suppressor PTEN regulates cell size and proliferation via the actin cytoskeleton.'. You mention a gene that is new to FlyBase, Pten. Do you have a map location for Pten? It is nice if we can keep as many gene records as possible anchored to the map. Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC-035 Dear Rachel DPTEN maps to 31B/C, possibly 31C1. It has very recently been sequenced by BDGP (AC005454). This P1 clone contains primarily proximal 2L sequence - Dror lies just a few kilobases distal to DPTEN. We are waiting to hear about the fate of a manuscript submitted on this gene, before submitting the cDNA sequence. If you require any further information, please let me know. Best wishes Clive
