Subject: Helping FlyBase: ADRC-60, 311A and 632A Dear Doug, We are currently curating the abstracts for the upcoming 41st (Pittsburgh) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstracts: 'PERK, a newly discovered eIF-2 alpha kinase is a ER transmembrane protein.' 'ER stress induces phosphorylation of eIF-2 alpha, repression of protein synthesis, and induction of ER chaperone genes.' and 'Signal transduction pathway mediating the endoplasmic reticulum unfolded protein response: IRE1 and the ER chaperones.' You mention two genes that are new to FlyBase, Perk and Ire. Do you have a map locations for Perk and Ire? This is a data class we like to track, if possible. Thank you for your help, with best wishes, Rachel. Subject: Re: Helping FlyBase: ADRC-60, 311A and 632A Rachel, PERK is located at 83A1-3; Reference, Unpublished Zhang, P. and Cavener, D.R. IRE1 is located at 92B1-B7; Reference unpublished Geething, N. and Cavener, D.R. We should be submitting sequence/transcript mapping data to Genbank shortly. Cheers, Doug Douglas R.
