CD151 molecule (Raph blood group), also known as CD151 (Cluster of Differentiation 151), is a human gene.[5]


The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins and other transmembrane 4 superfamily proteins. It is involved in cellular processes including cell adhesion and may regulate integrin trafficking and/or function. This protein enhances cell motility, invasion and metastasis of cancer cells. Multiple alternatively spliced transcript variants that encode the same protein have been described for this gene.[5] Abnormalities in CD151 have been implicated in a form of epidermolysis bullosa.[6][7]

CD151 has been shown to interact with CD46.[8]
