Post-translational modificationi

Phosphorylated on serine residues. Phosphorylation of Ser-122 is strongly stimulated by hypoxia (By similarity).By similarity
Ubiquitinated; subsequent to hypoxia-dependent phosphorylation of Ser-122, ubiquitination targets the protein for rapid degradation via the ubiquitin system. This process may be characteristic for microvascular endothelial cells, since it could not be observed in large vessel endothelial cells (By similarity).By similarity

Interactioni

Subunit structurei

Efficient DNA binding requires dimerization with another bHLH protein. Forms heterodimers with TCF3. Binds to the LIM domain containing protein LMO2 and to DRG1. Can assemble in a complex with LDB1 and LMO2. Component of a TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3. Interacts with SBNO2; this interaction inhibits TAL1 occupancy of the DCSTAMP promoter, leading to the activation of the DCSTAMP promoter by the transcription factor MITF.By similarity
