psq | Pipsqueak, isoform M; Pipsqueak (psq) encodes a transcription factor that regulates chromatin silencing. It mediates the interaction of Polycomb group (Pc-G) members with Pc-G response elements. (1123 aa) | ||||
Rpb3 | RNA polymerase II 33kD subunit; DNA-directed 5'-3' RNA polymerase activity; RNA polymerase II activity; protein dimerization activity; DNA binding. It is involved in the biological process described with: transcription by RNA polymerase II; cellular response to heat. (275 aa) | ||||
b | Black (b) encodes an aspartate 1-decarboxylase. Mutations of b result in viable flies with a cuticular melanization phenotype. (575 aa) | ||||
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) |
