Background: TSPAN8

Tetraspanin-8 (TSPAN8), also known as TM4SF3 and human tumor-associated antigen CO-0029, is a member of the transmembrane 4 superfamily. It is a cell surface 27‑34 kDa glycoprotein with 4 transmembrane segments, and a large extracellular loop (LEL) domain from amino acids (aa) 106‑206. Both the N- and C-termini are intracellular. TSPAN8 is expressed by multiple tumor types as well as smooth and skeletal muscle cells, endothelial cells, hematopoietic progenitor cells and non-keratinized squamous epithelium. As with other TSPAN family molecules, TSPAN8 acts as an organizer of microdomains in membranes. Molecules that may be found in these domains include CD151 (another TSPAN family member), beta 1 Integrins, Integrin alpha 4 beta 6, EpCAM, and CD13. TSPAN8 would appear to remove Integrins from the cell surface, facilitating cell motility which, in the case of tumor cells, results in metastasis. TSPAN8 shares 53% aa sequence identity with both mouse and rat TSPAN8.
