What is
MYOSTATIN
Myostatin is a member of a family of secreted proteins, called the transforming growth factor β or TGF β superfamily. These proteins control cell proliferation (the process of generating more cells) and cell differentiation (the process of changing from an ‘immature’ cell, or precursor stem cell, into a specialised cell, like skeletal muscle). Myostatin has been shown to be involved in the control of muscle proliferation and differentiation.
In what way does myostatin control muscle growth and differentiation?
Myostatin protein is expressed predominantly in skeletal muscle, and negatively regulates (‘keeps at bay’) muscle growth. It does this by controlling muscle specific gene expression patterns, and by limiting the activity of an enzyme called AKT1. AKT1 is an indirect target of insulin growth factor 1 (IFG-1) and is involved in the PI3K and mTOR signaling that controls nutrient sensing, protein synthesis, and muscle hypertrophy.
