Background: TSPAN8

Tetraspanin-8 (TSPAN8), also known as TM4SF3 and human tumor-associated antigen CO-0029, is a member of the transmembrane 4 (tetraspanin) superfamily. It is a cell surface 27 - 34 kDa protein with intracellular N- and C-termini, 4 transmembrane segments and a large extracellular loop (LEL) domain from aa 106-206. TSPAN8 is involved in integrin-mediated cell motility, metastasis, cell proliferation and differentiation, and is over-expressed in carcinomas including hepatocellular carcinoma and colon cancer. Polymorphisms have variably been associated with type II diabetes, bipolar disorder and schizophrenia. Human TSPAN8 shares 70% aa sequence identity with mouse and rat TSPAN8.

• Long Name:

  Tetraspanin 8/Transmembrane 4 Superfamily, Member 3

• Entrez Gene IDs:

• Alternate Names:

  CO-029; tetraspanin 8; TM4SF3; TM4SF3tspan-8; Transmembrane 4 superfamily member 3tetraspanin-8; TSPAN8; Tspan-8; Tumor-associated antigen CO-029
