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.

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] Recommended dilutions: Immunofluorescence: 1/200 - 1/1000. ELISA: 1/10000. Not yet tested in other applications.. Cellular localization: Nucleus, nucleoplasm . Nucleus, nucleolus . Interaction with MDFIC sequesters it into the nucleolus, preventing the transcription factor activity. Phosphorylation by PLK4 disrupts the interaction with MDFIC and releases it from the nucleolus, leading to transcription factor activity (By similarity). .
