products description :
Mouse anti Human CD81 antibody, clone 1D6 recognizes human CD81, a 26kDa cell surface antigen also known as TAPA-1, and a member of the tetraspanin family. CD81 is widely expressed on human leucocytes and appears to be involved in a variety of cellular leucocytes including activation, proliferation and differentiation. Mouse anti Human CD81 antibody, clone 1D6 is a potent CD81 reagent, induces homotypic adhesion and has powerful anti-proliferative effects.

ncbi summary :
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 that is known to complex with integrins. This protein appears to promote muscle cell fusion and support myotube maintenance. Also it may be involved in signal transduction. This gene is localized in the tumor-suppressor gene region and thus it is a candidate gene for malignancies. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]
uniprot summary :
CD81: May play an important role in the regulation of lymphoma cell growth. Interacts with a 16-kDa Leu-13 protein to form a complex possibly involved in signal transduction. May act as the viral receptor for HCV. Defects in CD81 are the cause of immunodeficiency common variable type 6 (CVID6); also called antibody deficiency due to CD81 defect. CVID6 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. Belongs to the tetraspanin (TM4SF) family. Protein type: Membrane protein, integral; Membrane protein, multi-pass. Chromosomal Location of Human Ortholog: 11p15.5. Cellular Component: focal adhesion; membrane; integral to plasma membrane; plasma membrane; immunological synapse; vesicle. Molecular Function: protein binding. Biological Process: cell proliferation; virion attachment, binding of host cell surface receptor; entry of virus into host cell; regulation of immune response; positive regulation of peptidyl-tyrosine phosphorylation; protein localization; activation of MAPK activity; positive regulation of cell proliferation; positive regulation of 1-phosphatidylinositol 4-kinase activity; phosphatidylinositol biosynthetic process; positive regulation of B cell proliferation; phosphatidylinositol metabolic process. Disease: Immunodeficiency, Common Variable, 6
