Myf5
Encyclopedia
Myf5 is a protein
with a key role in regulating muscle differentiation
.
Myf5 belongs to a family of proteins known as myogenic regulatory factors
(MRFs). These bHLH (basic helix loop helix) transcription factor
s act sequentially in myogenic differentiation. MRF family members include Myf5, MyoD
(Myf3), myogenin
, and MRF4 (Myf6).
Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Myogenesis
Myogenesis is the formation of muscular tissue, in particular during embryonic development.Muscle fibers form from the fusion of myoblasts into multi-nucleated fibers . In the early development of an embryo these myoblasts will proliferate if enough fibroblast growth factor is present...

Myogenic regulatory factors
Myogenic regulatory factors are basic-helix-loop-helix transcription factors that regulate myogenesis: MyoD, Myf5, myogenin, and MRF4.These proteins contain a conserved basic DNA binding domain that binds the E box DNA motif . They dimerize with other HLH containing proteins through an HLH-HLH...
