CD82 also known as KAI1 is a member of the tetraspanin family of proteins. It has a molecular mass of approximately 29 to 30 kDa. This protein is widely expressed on the surface of various cell types such as epithelial cells lymphocytes and endothelial cells. It features four transmembrane domains implying a role in organizing membrane microdomains. CD82 is known for its role in promoting cell adhesion and motility through its involvement in protein-protein interactions on the cell surface.
Biological function summary
CD82 plays a significant role in regulating cell signaling and communication during tumor progression and metastasis. It participates in the formation of tetraspanin-enriched microdomains by associating with other tetraspanins and integrins influencing the cellular microenvironment. Additionally CD82 impacts immune cell interactions by modulating activities of T cells and B cells. Despite not being the predominant component in any major protein complex CD82 influences many cellular processes by regulating diverse signaling pathways.
Pathways
CD82 modulates both the PI3K-Akt signaling pathway and the Wnt signaling pathway. These pathways are critical in controlling cellular processes like growth and survival contributing to the metastasis-suppressive effects of CD82. In these contexts CD82 associates with proteins such as integrins and cadherins which facilitate its regulation of signal transduction and cellular dynamics. CD82's role in these pathways shows its importance in controlling cancer cell behavior and immune system interactions.
CD82 has been linked to various cancers particularly prostate cancer and melanoma. Its downregulation or loss often correlates with tumor progression and metastasis indicating its function as a metastasis suppressor. In cancer CD82 interacts with proteins like epidermal growth factor receptor (EGFR) and other integrins affecting disease progression by altering cell adhesion migration and invasion. CD82’s expression level serves as a potential biomarker for cancer prognosis and treatment outcomes.
