Subject: Curation of 36th Ann. Dros. Conf. abstract 113A Dear Kathleen Fitzpatrick, I am a curator of FlyBase at the Cambridge, England, site working with Prof. M. Ashburner. I shall be curating the abstracts from the 36th Ann. Dros. Res. Conf. Your abstract, 113A, discusses several PTP genes. In the database we have five protein tyrosine phosphatase genes. Could you tell me which of these, or if you used all of the Ptp genes in your study during oogenesis. Ptp4E, Ptp10D, Ptp36DE, Ptp61F or Ptp99A Any information you can give me will be greatly appreciated. Many thanks, Eleanor Whitfield. Subject: Re: Curation of 36th Ann. Dros. Conf. abstract 113A Dear Eleanor Whitfield; The genes we have looked at during oogenesis are: DPTP61F, DPTP69D (this is the DPTP originally picked up by Saito along with DLAR), DPTP38A(DLAR), DPTP99A, DPTP10D, DPTP4E, DPTP36E (we have refined the position since our last presentation), and csw. The only phosphatases we didn't use are string and twine, whose oogenesis expression patterns are already known. I hope this is helpful to you in curating the abstracts. If there are any other questions, please do not hesitate to contact me. Kathleen Fitzpatrick.
