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 and may have a role in the control of neurite outgrowth. It is known to complex with integrins. This gene is associated with X-linked mental retardation and neuropsychiatric diseases such as Huntington's chorea, fragile X syndrome and myotonic dystrophy.,TSPAN7,A15,CCG-B7,CD231,DXS1692E,MRX58,MXS1,TALLA-1,TM4SF2,TM4SF2b,Cancer,Signal Transduction,Endocrine & Metabolism,Amino acid metabolism,Immunology & Inflammation,CD markers,TSPAN7
