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.
