CD37 Overview

CD37 is a cell surface glycoprotein and a member of the tetraspanin (transmembrane 4 superfamily) protein family. It is highly expressed on mature B cells and plays a key role in immune regulation, including cell development, activation, growth, motility, and humoral/cellular immune responses. CD37 forms complexes with integrins and other tetraspanins to create tetraspanin-enriched microdomains (TEMs). It has been implicated in diseases such as Mantle Cell Lymphoma and Diffuse Large B-Cell Lymphoma, where patients lacking CD37 have worse clinical outcomes.
