Background

Human A33, also known as GPA33, is a 43 kDa type I transmembrane glycoprotein that belongs to the CTX (cortical thymocyte marker in Xenopus) family of cell adhesion molecules within the immunoglobulin superfamily. Other family members include CXADR, ESAM, BT-IgSF, CD2, and JAM-A, -B, and -C. The extracellular domain (ECD) of human A33 is 214 amino acids (aa) in length and contains one V-type and one C2-type Ig-like domain. This ECD shares 80%, 74%, and 71% aa sequence identity with canine, bovine, and mouse A33 ECD, respectively. A33 is likely to be involved in cell-cell adhesion between epithelial cells.
