Also known as eHandThing1HxtbHLHa27
Summary
HAND1 (heart and neural crest derivatives expressed 1, HGNC:4807) is a protein-coding gene on chromosome 5q33.2, encoding Heart- and neural crest derivatives-expressed protein 1 (O96004). Transcription factor that plays an essential role in both trophoblast giant cell differentiation and in cardiac morphogenesis.
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.

UniProt curated annotations — full annotation on UniProt →
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.
Subunit / interactions. 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. Interacts with SOX15; the interaction enhances HAND1-induced differentiation of trophoblast giant cells.
Subcellular location. Nucleus. Nucleoplasm. Nucleolus.
Tissue specificity. Heart.
Post-translational modifications. Phosphorylation by PLK4 disrupts the interaction with MDFIC and leads to translocation into the nucleoplasm, allowing dimerization and transcription factor activity.
