Description

General description

Somatoliberin (UniProt: P09916; also known as Growth hormone-releasing factor, GRF, Growth hormone-releasing hormone, GHRH) is encoded by the Ghrh gene (Gene ID: 29446) in rat. GHRH F is released by the hypothalamus and acts on the adenohypophyse to stimulate the secretion of growth hormone. The release of growth hormone from pituitary gland depends of the interplay between the stimulatory action of GHRH and inhibitory action of somatotropin release inhibiting factor (SRiF) or somatostatin. These two neurohormones are shown to be released in a reciprocal manner from the median eminence into the portal circulation and result in ultradian rhythmic release pattern of growth hormone.. Post-translational removal of the signal peptide (aa 1-19) and the two propeptide sequences (aa 20-30) and aa 75-104) releases the 43 aa mature Somatoliberin (aa 31-73), which functions as a ligand to stimulate growth hormone (GH) release from the pituitary. Variant receptors for GHRH have been found in several types of tumors, and antagonists of these receptors are shown to block the growth of the tumors. Defects in Ghrh gene are a known to cause of dwarfism, while hypersecretion of the encoded GHRH can lead to gigantism.
