Human Growth Hormone (GH)
Product Description:
Human growth hormone (GH), also known as
somatotropin, is synthesized in the anterior pituitary as a 217-amino acid
precursor, which is further cleaved to generate the mature 191-amino acid (22
kDa) cytokine. Through binding to the GH receptor, it exhibits potent
pleiotropic biological effects in an IGF1-dependent and -independent manner.
Prominent signal transduction events activated by GH include the JAK/STAT and
MAPK/ERK pathways, culminating in IGF1 production and growth promotion. Other
significant effects of GH are activation of lipolysis, stimulation of protein
synthesis, and augmentation of immune function. Since this function of GH is
generally anabolic, it has been explored clinically to treat short stature in
children. Bovine GH is used to increase milk production in dairy cows. Human
and bovine GH amino acid sequences are 67% homologous. The human GH is
over-produced and purified from E. coli. The product is for research use only.
