Nascent polypeptide-associated complex subunit alpha, muscle-specific form (NACA)

Cardiac- and muscle-specific transcription element. May act to modulate the expression of genes involved in the development of myotubes.

Plays a critical role in ventricular cardiomyocyte growth and regulates postnatal skeletal muscle growth and regeneration. Involved in the organized assembly of thick and thin filaments of myofibril sarcomeres (By similarity).
