Molecular function

GHIH receptor activity, SRIF receptor activity, SST receptor activity, growth hormone-inhibiting hormone receptor activity, somatotrophin release inhibiting factor receptor activity

Combining with somatostatin to initiate a change in cell activity. Somatostatin is a peptide hormone that regulates the endocrine system by signaling via G protein-coupled somatostatin receptors. Somatostatin has two active forms produced by proteolytic cleavage: a 14 amino acid peptide (SST-14) and a 28 amino acid peptide (SST-28).
