The protein encoded by this gene belongs to the basic helix-loop-helix family of transcription factors. This gene product is one of two closely related family members, the HAND proteins, which are asymmetrically expressed in the developing ventricular chambers and play an essential role in cardiac morphogenesis. Working in a complementary fashion, they function in the formation of the right ventricle and aortic arch arteries, implicating them as mediators of congenital heart disease. In addition, it has been suggested that this transcription factor may be required for early trophoblast differentiation. [provided by RefSeq, Jul 2008]
Protein class

Human disease related genes, Transcription factors

Predicted location

Intracellular

Single cell type specificity

Cell type enriched (Cardiomyocytes)

Immune cell specificity

Not detected in immune cells

Cell line specificity

Group enriched (SH-SY5Y, SuSa)

Interaction

Efficient DNA binding requires dimerization with another bHLH protein. Forms homodimers and heterodimers with TCF3 gene products E12 and E47, HAND2 and HEY1, HEY2 and HEYL (hairy-related transcription factors). Interacts with MDFIC (By similarity). Interacts with SOX15; the interaction enhances HAND1-induced differentiation of trophoblast giant cells (By similarity).

Molecular function

Activator, Developmental protein, DNA-binding
