ADVANCES IN THE RESEARCH OF STANNIOCALCIN PRODUCED BY THE CORPUSCLES OF STANNIUS IN TELEOST
鱼类斯钙素的研究进展

This paper reviewed the recent researches on the stanniocalcin (STC) produced by the corpuscles of Stannius in teleost.STCs are homodimeric glycoprotein hormones with apparent molecular weight ranging from 46kDa(chum salmon)to 56kDa (rainbow trout) in native form and 23-28kDa in the reduced condition.The amino acid sequence analyses of STCs and cDNAs have revealed that reduced STCs (monomer) consist of 179 (chum salmon),223 (coho salmon) and 231 (Australian eel) amino acid residues,respectively.Other studies show that secretion of STC is regulated by calcium concentrations and that the cholinergic nerves are involved in the release of STC.
