Mouse monoclonal antibody to human CD316 antigen [1E4]: IgG

CD316 antigen forms highly proximal, specific, and stoichiometric complexes with CD81 and CD9. It may play a key role in the diverse functions of CD81 and CD9 such as oocytes fertilisation or hepaptitis C virus function. It may regulate proliferation and differentiation of keratinocytes and may negatively regulate cell motility. It may also participate in the regulation of neurite outgrowth and maintenance of the neural network in the adult brain. CD316 antigen is a transmembrane protein that is expressed in brain, kidney, testis, liver and placenta with moderate expression in all other tissues. It is detected on a majority of B-cells, T-cells and natural killer cells but not on monocytes, polynuclear cells and platelets.
