The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as thetetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic transmembrane domains. Tetraspanins mediate signal transduction events that play a role in the regulation of immune responses, cell development, activation, growth and motility.[7][8][9][10] CD37 expression is restricted to cells of the immune system, with highest abundance on mature B cells, and lower expression is found on T cells and myeloid cells. CD37 is a cell surfaceglycoprotein that is known to complex withintegrins and other transmembrane 4 superfamily proteins. Alternate splicing results in multiple transcript variants encoding different isoforms.[6] CD37 controls both humoral[11][12] and cellular immune responses.[13][14][15] CD37-deficiency in mice leads to spontaneous development on B cell lymphoma,[16] and patients with CD37-negative lymphomas have a worse clinical outcome.[17]
