Myogenic factor 6 (herculin) is a protein that in humans is encoded by the MYF6 gene. [5] Also known in the medical literature as MRF4 and herculin), MYF6 is a myogenic regulatory factor (MRF) in the process known as myogenesis.[6][7]

Function

MYF6 is a member of the myogenic factors (MYF) family that regulate myogenesis and muscle regeneration. Myogenics factor are basic helix-loop-helix (bHLH) transcription factors. MYF-6 is a gene that encodes a protein involved in the regulation of myogenesis. Specifically, it induces the maturation of myotubes into myofibers. The portion of the protein integral to myogenesis regulation is a basic helix-loop-helix (bHLH) domain that is conserved among all of the genes in the MRF family.

MYF-6 is expressed exclusively in skeletal muscle, and it is expressed at a higher levels in adult skeletal muscle than all of the other genes in the muscle regulatory factor factor gene family. MYF-6 is different from the other myogenic regulatory factor genes due to its two-phase expression. Initially, MYF-6 is transiently expressed along with MYF-5 in the somites during the early stages of myogenesis.[8] However, it is primarily expressed postnatally. This suggests that it serves an important role in the maintenance and repair of adult skeletal muscle.[8] The role of MYF-6 expression in the somites during embryogenesis is currently unknown.

The MYF-6 gene is physically linked to the MYF-5 gene on chromosome 12, and mutations in the MYF-6 gene typically exhibit reduced levels of MYF-5.[9] Despite reductions in muscle mass of the back, MYF6 mutants still exhibit fairly normal skeletal muscle. While this demonstrates that MYF-6 might not be essential for the formation of myofibers, it is thought that myogenin compensates for the absence of functional MYF-6.[10]

Clinical significance

Mutations in the MYF6 gene are associated with autosomal dominant centronuclear myopathy (ADCNM) and Becker's muscular dystrophy.[11]
