CD82 (KAI1) is a highly glycosylated membrane protein belonging to the tetraspanins. The tetraspanins are a family of proteins that possesses four transmembrane domains, namely, the NH2- and COOH-terminal cytoplasmic domains, and two extracellular loops. A few tetraspanins, including CD151, tetraspanin 8, CD82, and CD9, are involved in tumor metastasis. CD82 is a metastasis suppressor implicated in cell fusion, adhesion, migration, apoptosis, and cell morphology alterations. It has attracted much attention in various human cancers, such as prostate, pancreatic, lung, gastric, hepatic, and colorectal cancers. As a membrane protein, CD82 interacts with integrins, other tetraspanins (CD9, CD63, and CD81), cell-surface molecules (CD4, CD8, CD19, and CD21), and MHC class I and class II, which includes CD82 into a newly defined tetraspanin web Two types of PTMs, namely, glycosylation and palmitoylation, occur on CD82. The palmitoylation is reportedly an important PTM for its motility- and invasiveness-inhibitory activity. On the other hand, CD82 has three potential N-glycosylation sites located at the large extracellular loop. CD82N- glycosylation has been previously shown to play a potent role in cell adhesion and motility. White et al. found that CD82 has distinct heterogeneous protein band patterns in various human cancer cell lines, which are most likely associated with N-glycosylation. Lysate of human CD82 transfected 293T cells
CD82 (h): 293T Lysate is suitable as a Western Blotting positive control for human reactive CD82 antibodies. Recommended use: 10-20 µl per lane. Control 293T Lysate: 293LYS is available as a Western Blotting negative control lysate derived from non-transfected 293T cells.
