Transcriptional activator which probably serves as a general switch factor for erythroid development. It binds to DNA sites with the consensus sequence [AT]GATA[AG] within regulatory regions of globin genes and of other genes expressed in erythroid cells. May form homodimers or heterodimers with other isoforms. Interacts (via the N-terminal zinc finger) with ZFPM1. 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 EP300. Erythrocytes. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
