Cell surface A33 antigen is a protein that in humans is encoded by the GPA33 gene.{{cite journal |vauthors=Heath JK, White SJ, Johnstone CN, Catimel B, Simpson RJ, Moritz RL, Tu GF, Ji H, Whitehead RH, Groenen LC, Scott AM, Ritter G, Cohen L, Welt S, Old LJ, Nice EC, Burgess AW | title = The human A33 antigen is a transmembrane glycoprotein and a novel member of the immunoglobulin superfamily | journal = Proc Natl Acad Sci U S A | volume = 94 | issue = 2 | pages = 469–74 |date=Mar 1997 | pmid = 9012807 | pmc = 19536 | doi =10.1073/pnas.94.2.469 | bibcode = 1997PNAS...94..469H | doi-access = free }}{{cite journal |vauthors=Ritter G, Cohen LS, Nice EC, Catimel B, Burgess AW, Moritz RL, Ji H, Heath JK, White SJ, Welt S, Old LJ, Simpson RJ | title = Characterization of posttranslational modifications of human A33 antigen, a novel palmitoylated surface glycoprotein of human gastrointestinal epithelium | journal = Biochem Biophys Res Commun | volume = 236 | issue = 3 | pages = 682–6 |date=Sep 1997 | pmid = 9245713 | doi = 10.1006/bbrc.1997.6966 }}{{cite web | title = Entrez Gene: GPA33 glycoprotein A33 (transmembrane)| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=10223}}
The glycoprotein encoded by this gene is a cell surface antigen that is expressed in greater than 95% of human colon cancers. The open reading frame encodes a 319-amino acid polypeptide having a putative secretory signal sequence and 3 potential glycosylation sites. The predicted mature protein has a 213-amino acid extracellular region, a single transmembrane domain, and a 62-amino acid intracellular tail. The sequence of the extracellular region contains 2 domains characteristic of the CD2 subgroup of the immunoglobulin (Ig) superfamily.
