Human GPA33 (22-139) Protein, hFc Tag

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. [provided by RefSeq, Jul 2008]Molecular Weight : The protein has a predicted molecular mass of 39.3 kDa after removal of the signal peptide. The apparent molecular mass of GPA33 (22-139) -hFc is approximately 35-55 kDa due to glycosylation.Tag :C-Human Fc tag
