Anti-HAND1 Antibody Picoband®

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.

HAND1; BHLHA27; EHAND; Heart- and neural crest derivatives-expressed protein 1; Class A basic helix-loop-helix protein 27; bHLHa27; Extraembryonic tissues, heart, autonomic nervous system and neural crest derivatives-expressed protein 1; eHAND

A synthetic peptide corresponding to a sequence at the C-terminus of human HAND1. Human HAND1 shares 90% and 93.8% amino acid (aa) sequence identity with mouse and rat HAND1, respectively.
