MYOD1(redirected from bHLHc1)
MYOD1A gene on chromosome 11p15.4 that regulates myogenesis by encoding MyoD1, a nuclear phosphoprotein with partial homology to the myc family of oncoproteins, which binds to the enhancer sequences of the muscle-specific creatine phosphokinase gene, inhibiting DNA synthesis and cell proliferation. MyoD1 belongs to the basic helix-loop-helix (bHLH) transcription factor family and the myogenic factors subfamily. It regulates muscle cell differentiation by inducing cell cycle arrest, a prerequisite for myogenesis, and is involved in muscle regeneration.
