CC   -!- FUNCTION: Plays an important role in growth control. Its major role in
CC       stimulating body growth is to stimulate the liver and other tissues to
CC       secrete IGF-1. It stimulates both the differentiation and proliferation
CC       of myoblasts. It also stimulates amino acid uptake and protein
CC       synthesis in muscle and other tissues (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the somatotropin/prolactin family.
CC       {ECO:0000305}.
