Subject: ADRC-682C Dear Terence, 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: 'Analysis of the roles of a family of Drosophila skp1 homologs in cell cycle progression' You mention four genes that are new to FlyBase, skpA, B, C and D. Do you have a map location for any of these genes? 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-682C Dear Rachel, Thanks for your interest in the Drosophila skp genes. A lot of the information for dskpA ties into the Berkeley database. EP(X)1423 is inserted into the 5' UTR of dskpA, originally indicated by end sequencing done by the BDGP. The sequence from EP(X)1423 also ties into the sequence of cosmid 115C2, in which the EDGP identified an ORF homologous to SKP1. There are also a bunch of ESTs, but I'm not sure you keep those on the Flybase map. I'll add that dskpA is located at 1B10-14 on the polytene map, so you can also anchor that cosmid sequence. Imprecise excisions of EP(X)1423 are lethal, and fail to complement: Df(1)svr T(1;Y)B106, y (the Df(1) half) Df(1)su(s)83 but are complemented by: Df(1)y74k24.1 The complementation data is consistent with the polytene localization. As far as the other homologs, I'll send along that information when I publish them, since I know other people are interested in the SKP1 genes and may not know about the other family members. I have no objections to you adding the above data to Flybase at this point, since almost all of it can be derived from the BDGP data anyway (except for the polytene localization). Let me know if you want any other pieces of data clarified. \-Terence Subject: Re: ADRC-682C Dear Terence, Thank you very much for the information about skpA. It is very useful indeed and allows me to rename the EG:115C2.4 gene (FBgn0025637) that is currently in FlyBase as skpA. I see no reason to doubt that they are the same thing. Not only that, but I can link the insertion we currently have as P{EP}EP1423 (FBti0007441) to an allele of skpA, which we should call skpAEP1423, to reflect the insertion into the 5' UTR (even if the insertion is phenotypically silent). Brilliant. We do indeed capture links between ESTs and genes so if it is easy for you to provide me with the relevant EST identifiers that would be the icing on the cake. Your mail will be curated as a personal communication to FlyBase. Many thanks, Rachel.
