Description
Mouse CD81 Recombinant Protein (N-GST & C-His)
Mouse CD81 Recombinant Protein (N-GST & C-His) is a recombinant protein expressed in E. coli, spanning Phe113-Lys201, with an N-terminal GST tag and a C-terminal His tag. Predicted molecular weight: 37.98 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. CD81 antigen is a ~25 kDa protein. Structural component of specialized membrane microdomains known as tetraspanin-enriched microdomains (TERMs), which act as platforms for receptor clustering and signaling. For research use only.
Essential for trafficking and compartmentalization of CD19 receptor on the cell surface of activated B cells. Upon initial encounter with a microbial pathogen, enables the assembly of CD19-CR2 and B cell receptor complexes at signaling TERMs, lowering the threshold dose of antigen required to trigger B cell clonal expansion and humoral immune response. In T cells, associates with CD4 or CD8 coreceptors and defines the maturation state of antigen-induced synapses with B cells. Facilitates localization of CD3 in these immune synapses, required for costimulation and sustained activation of T cells, preferentially triggering T helper type 2 immune response.
