UniProt ID: Q90477
FUNCTION: May act as a transcriptional activator that promotes transcription of muscle-specific target genes and plays a role in muscle differentiation. {ECO:0000250}.
SUBUNIT: Efficient DNA binding requires dimerization with another bHLH protein.
INTERACTION: Q90463:her1; NbExp=2; IntAct=EBI-16009646, EBI-16009629; Q9I9K1:her7; NbExp=2; IntAct=EBI-16009646, EBI-16009727; Q6P0J1:hes6; NbExp=2; IntAct=EBI-16009646, EBI-16009592;
SUBCELLULAR LOCATION: Nucleus.
TISSUE SPECIFICITY: From mid-gastrula to just before somite formation, expressed in cells adjacent to axial mesoderm. Subsequently, during the anterior-to-posterior wave of somite formation and maturation, expressed within particular regions of each somite. Expressed in both muscle and non-muscle cells. {ECO:0000269|PubMed:12524040, ECO:0000269|PubMed:8565839}.
