Subcellular location [CC]Cell membrane {ECO:0000269|PubMed:23269669};
Single-pass type I membrane protein {ECO:0000269|PubMed:23269669}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:23269669};
Single-pass type I membrane protein {ECO:0000269|PubMed:23269669}. Note=The 145 kDa plasma membrane form of GUCY2C 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. {ECO:0000269|PubMed:23269669}.
