Trl | Transcription factor GAGA; Transcriptional activator that functions by regulating chromatin structure. Overcomes the repressive effects of chromatin by promoting the open chromatin conformation in promoter gene regions, thereby allowing access to other transcription factors. Binds to DNA Polycomb response elements (PREs) at the bithorax complex and to the proximal region of the engrailed promoter, and positively regulates transcription of many genes including homeotic ones. Binds to the DNA sequence (GA)n, with optimal binding to the pentamer 5'-GAGAG-3'. Binds DNA as an oligomer. May [...] (623 aa) | ||||
ppk19 | Pickpocket 19 (ppk19) encodes a predicted member of the Degenerin/Epithelial Sodium Channel family protein. In the larval stage, it is expressed in the terminal organ for salt taste and tracheal cells for liquid clearance. In the adult stage it functions in salt taste likely through its expression in the chemical-sensing epithelia in the leg segment and wing blade. (511 aa) |
