Recombinant Human Heat-stable enterotoxin receptor (GUCY2C), Truncated

Uniprot Id

P25092

Target Species

Human

Target Name

GUCY2C

Target Full Name

Guanylyl cyclase C

Target Function

Receptor for the E.coli heat-stable enterotoxin (E.coli enterotoxin markedly stimulates the accumulation of cGMP in mammalian cells expressing GC-C). Also activated by the endogenous peptides guanylin and uroguanylin.

Target Involvement

Diarrhea 6 (DIAR6); Meconium ileus (MECIL)

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein. Endoplasmic reticulum membrane; Single-pass type I membrane protein. Note=The 145 kDa plasma membrane form of GC-C contains sialic acid and galactose residues, while a differencially glycosylated 130 Kda form is a high mannose form that is resident in the endoplasmic reticulum and may serve as the precursor for the cell surface form.

Target Protein Families

Adenylyl cyclase class-4/guanylyl cyclase family

Target Research Area

Metabolism

Target Synonyms

GC-C; Guanylyl cyclase C; GUC2C; GUC2C_HUMAN; GUCY2C; Heat stable enterotoxin receptor; Heat-stable enterotoxin receptor; hSTAR; Intestinal guanylate cyclase; STA receptor

Target Background

This gene encodes a transmembrane protein that functions as a receptor for endogenous peptides guanylin and uroguanylin, and the heat-stable E. coli enterotoxin. The encoded protein activates the cystic fibrosis transmembrane conductance regulator. Mutations in this gene are associated with familial diarrhea (autosomal dominant) and meconium ileus (autosomal recessive).
