Anti-HAND1

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. Protein function: Transcription factor that plays an essential role in both trophoblast giant cell differentiation and in cardiac morphogenesis. Binds the DNA sequence 5'-NRTCTG-3' (non-canonical E-box). Acts as a transcriptional repressor of SOX15. In the adult, could be required for ongoing expression of cardiac-specific genes (PubMed:9931445). [The UniProt Consortium]
