Background: TSPAN8

TSPAN8 (Tetraspanin-8), also known as TM4SF3 and CO-029, is a 27-33 kDa member of the tetraspanin family of proteins. As evidenced by its name, it is a 4-transmembrane (glyco)protein that is found on/in multiple tumor types as well as smooth and skeletal muscle, endothelium and hematopoietic progenitor cells. All 4-transmembrane proteins are not tetraspanins. Tetraspanins are characterized by the presence of a very short intracellular C- and N-terminus, and a very long extracellular (or LEL) domain linking the 3rd and 4th transmembrane segments. On TSPAN8 this domain is 98 amino acids (aa) in length and represents 42% of the entire length of mouse TSPAN8 (or 235 aa). TSPAN8, like other tetraspanins, forms the backbone of a network that allows molecule interactions on (or in) plasma membranes. This ability is dependent upon molecule palmitoylation and creates a microdomain (or TEM) that is distinct from typical membrane rafts, the latter of which is characterized by the presence of GPI-linked proteins and the molecule caveolin. Within this TEM, TSPAN8 may form homodimers, and is known to interact with multiple molecule types, including CD151, CD81, CD9, CD13, EpCAM, EWI-F, MMP-9, Meprin-beta, Rictor, TACE and the integrins alpha 3(CD49c) beta 1, alpha 6 beta 4 and alpha 4(CD49d) beta 1. Such interactions appear to positively or negatively modulate individual molecule activity. These interactions are generally described within the context of exosomes, 30-100 nm membrane-bound vesicles that are released from multiple cell types. TSPAN8-containing exosomes are reported to either facilitate cell motility or act as an antiapoptotic agent for target cells. Over aa 106-203 constituting the LEL, mouse TSPAN8 shares 58% and 73% aa sequence identity with human and rat TSPAN8, respectively.
