Gata1, Erythroid transcription factor
Also Known as
GATA1_MOUSE, Gata1, Gf-1
Transcriptional activator or repressor which probably serves as a general switch factor for erythroid development. It binds to DNA sites with the consensus sequence 5'-[AT]GATA[AG]-3' within regulatory regions of globin genes and of other genes expressed in erythroid cells. Activates the transcription of genes involved in erythroid differentiation of K562 erythroleukemia cells, including HBB, HBG1/2, ALAS2 and HMBS (By similarity). May form homodimers or heterodimers with other isoforms. Interacts (via the N-terminal zinc finger) with ZFPM1 (By similarity). Interacts with GFI1B. Interacts with PIAS4; the interaction enhances sumoylation and represses the transactivational activity in a sumoylation-independent manner. Interacts with LMCD1. Interacts with CREBBP; the interaction stimulates acetylation and transcriptional activity in vivo. Interacts with BRD3. Interacts with MED1, CCAR1 and CALCOCO1. Interacts with EP300 (By similarity). Interacts with CEBPE (By similarity).
