Background: TSPAN31

Tetraspanin 31, or TSPAN31, belongs to a superfamily of proteins that is characterized by four transmembrane domains, three intracellular domains and two extracellular loops: a small extracellular loop (SEL) and a large extracellular loop (LEL). The extracellular loops form molecular webs that bring together cell surface proteins, facilitating the formation of stable and functional signalling complexes. Tetraspanins form microdomains on the plasma membrane that mediate diverse biological processes including adhesion, cell fusion, immune response, and tumor development (1-4). Human TSPAN31 consists of 210 amino acids, with the LEL region spanning residues 94-173. Within the LEL, human TSPAN31 shares 77% aa 74% aa sequence identity with mouse and rat TSPAN31-LEL, respectively.
