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) | ||||
nAChRbeta2 | Nicotinic Acetylcholine Receptor beta2 (nAChRbeta2) encodes a subunit of the nicotinic acetylcholine receptor, which is part of the superfamily of ligand-gated ion channels. These channels open to facilitate the passage of cations across synaptic membranes in response to the binding of their native ligand, acetylcholine. Mutations in nAChRbeta2 have been associated with resistance phenotypes to several neonicotinoid insecticides. (519 aa) |
