Actin, alpha skeletal muscle is a protein that in humans is encoded by the ACTA1 gene.^[5]^[6]

Template:PBB Summary

Skeletal actin gene expression

Skeletal alpha actin expression is induced by stimuli and conditions known to cause muscle formation.^[7] Such conditions result in fusion of committed cells (satellite cells) into myotubes, to form muscle fibers. Skeletal actin itself, when expressed, causes expression of several other "myogenic genes", which are essential to muscle formation.^[8] One key transcription factor that activates skeletal actin gene expression is Serum Response Factor ("SRF"), a protein that binds to specific sites on the promoter DNA of the actin gene.^[9] SRF may bring a number of other proteins to the promoter of skeletal actin, such as androgen receptor, and thereby contribute to induction of skeletal actin gene expression by androgenic (often termed "anabolic") steroids.^[10]

Interactions

Actin, alpha 1 has been shown to interact with TMSB4X,^[11]^[12] MIB2^[13] and PRKCE.^[14]
