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) | ||||
l(2)dtl | Protein lethal(2)denticleless; Substrate-specific adapter of a DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex required for cell cycle control. The DCX(DTL) complex, also named CRL4(CDT2) complex, mediates the polyubiquitination and subsequent degradation of E2f during S phase. E2f degradation is necessary to ensure proper development. Substrates require their interaction with PCNA for their polyubiquitination: substrates interact with PCNA via their PIP-box, leading to recruit the DCX(DTL) complex; Belongs to the WD repeat cdt2 family.
