Human CD151, also known as SFA-1, Tetraspanin-24, and GP27, is a palmitoylated glycoprotein in the tetraspanin superfamily. It is the first tetraspanin member to be identified as a promoter of cancer metastasis (1, 2), and it is found to participate in nearly all stages of cancer progression (3). CD-151 is normally expressed in endothelial cells, platelets, and frequently over-expressed in cancer cells (4). Mature CD-151 is a multi-pass membrane protein that contains four transmembrane domains, three cytoplasmic domains, and two extracellular loops. The region of amino acids (aa) 113-221 contains the largest extracellular loop (LEL) that involves in interacting with integrins and regulating integrin functions (5). Human CD151 LEL shares 88.9% and 87.0% aa identity with that of mouse and rat respectively. CD151 interacts with integrins such as alpha v beta 3, alpha 3 beta 1, alpha 6 beta 1, alpha 7 beta 1, and alpha 6 beta 4 to regulate their activities and thus resulting in modulation of adhesion, spreading, migration, angiogenesis, invasion and metastasis (1, 3-5). CD151 can also complex with immunoglobulin super family proteins and other tetraspanins such as CD9, CD81, and CD63 (3). Clinically, high levels of CD151 are correlated with poor prognosis in a variety of tumors (3, 4). CD151 has been implicated as a potential diagnostic marker in osteosarcoma and prostate cancer and a putative target for antibody-based immunotherapy (3). CD-151 is a key player in the formation of basement membranes in kidney and skin tissues; it is also associated with human papillomavirus (HPV) infection (6, 7).
