Ubx | Homeotic protein ultrabithorax; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Binds the consensus region 5'-TTAAT[GT][GA]-3'. This homeotic protein controls development of the cells in the posterior thoracic and first abdominal segments. It activates the synthesis of the decapentaplegic (DPP) growth factor; Belongs to the Antp homeobox family. (389 aa) | ||||
PK1-R | Pyrokinin-1 receptor; Receptor for the neuropeptide CAP-3/pyrokinin-1 (TGPSASSGLWFGPRL-amide). Also activated weakly by other neuropeptides terminating in the sequence PRL-amide including pyrokinin-2, Hug-gamma, and ecdysis-triggering-hormone-1. The activity of this receptor is mediated by G proteins which activate a phosphatidyl-inositol-calcium second messenger system. (430 aa) |
