Primary structure and functional expression of the human receptor for Escherichia coli heat-stable enterotoxin.

Abstract

Heat-stable enterotoxin (STa) produced by Escherichia coli induces intestinal secretion in mammals by binding to the brush border membrane of the small intestine and activating guanylyl cyclase. We report here the cloning and expression of a cDNA encoding the human receptor for STa. The receptor contains both an extracellular ligand binding site and a… (More)
