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, this transcription factor plays an important role in limb and branchial arch development. [provided by RefSeq, Jul 2008]
HAND2 (Heart And Neural Crest Derivatives Expressed 2) is a Protein Coding gene. Diseases associated with HAND2 include Familial Isolated Dilated Cardiomyopathy and Partial Trisomy Distal 4Q. Among its related pathways are NFAT and Cardiac Hypertrophy and TarBasePathway. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and protein heterodimerization activity. An important paralog of this gene is HAND1.
