Protein

Heat-stable enterotoxin receptor

Gene
Gucy2c, Guc2c
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Subcellular locationi

Cell membrane; Single-pass type I membrane protein. Endoplasmic reticulum membrane By similarity; 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 By similarity.
