Description

Molfile Inchi Smiles Synonyms: somatostatin aminopan growth hormone release-inhibiting factor somatotropin release-inhibiting hormone SRIF-14

A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal. Molecular weight: 1637.90 Formula: C76H104N18O19S2 CLOGP: -1.46 LIPINSKI: 3 HAC: 37 HDO: 22 TPSA: 613.23 ALOGS: -4.90 ROTB: 26
