Background

  • Function

    CD81 is a Structural component of specialized membrane microdomains known as tetraspanin-enriched microdomains (TERMs), which act as platforms for receptor clustering and signaling. Essential for trafficking and compartmentalization of CD19 receptor on the surface of activated B cells. Upon initial encounter with microbial pathogens, enables the assembly of CD19-CR2/CD21 and B cell receptor (BCR) complexes at signaling TERMs, lowering the threshold dose of antigen required to trigger B cell clonal expansion and antibody production. In T cells, facilitates the localization of CD247/CD3 zeta at antigen-induced synapses with B cells, providing for costimulation and polarization toward T helper type 2 phenotype. Present in MHC class II compartments, may also play a role in antigen presentation. Can act both as positive and negative regulator of homotypic or heterotypic cell-cell fusion processes. Positively regulates sperm-egg fusion and may be involved in acrosome reaction. In myoblasts, associates with CD9 and PTGFRN and inhibits myotube fusion during muscle regeneration. In macrophages, associates with CD9 and beta-1 and beta-2 integrins, and prevents macrophage fusion into multinucleated giant cells specialized in ingesting complement-opsonized large particles. Also prevents the fusion of mononuclear cell progenitors into osteoclasts in charge of bone resorption. May regulate the compartmentalization of enzymatic activities. In T cells, defines the subcellular localization of dNTPase SAMHD1 and permits its degradation by the proteasome, thereby controlling intracellular dNTP levels. Also involved in cell adhesion and motility. Positively regulates integrin-mediated adhesion of macrophages, particularly relevant for the inflammatory response in the lung; (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) in hepatocytes. Association with CLDN1 and the CLDN1-CD81 receptor complex is essential for HCV entry into host cell; (Microbial infection) Involved in SAMHD1-dependent restriction of HIV-1 replication. May support early replication of both R5- and X4-tropic HIV-1 viruses in T cells, likely via proteasome-dependent degradation of SAMHD1; (Microbial infection) Specifically required for Plasmodium falciparum infectivity of hepatocytes, controlling sporozoite entry into hepatocytes via the parasitophorous vacuole and subsequent parasite differentiation to exoerythrocytic forms[1][2][3][4][5][6][7][8][9][10].

  • Subunit

    Homodimer (PubMed:20375010). Part of a complex composed of CD19, CR2/CD21, CD81 and IFITM1/CD225 in the membrane of mature B cells. Interacts (via the second extracellular domain) with CD19; this interaction is initiated early during biosynthesis in the ER and enables trafficking of only properly folded CD19 (PubMed:1383329, PubMed:16449649). Part of a complex that includes MHC class II/HLA-DR molecules and IFITM1 (PubMed:8409388). Interacts with IFITM1 (PubMed:2398277, PubMed:26354436). Interacts with IFITM2 and IFITM3 (By similarity). Part of integrin-tetraspanin complex composed of CD9, CD81, beta-1 and beta-2 integrins in the membrane of monocyte/macrophages (PubMed:12796480). Interacts (via the second extracellular domain) with integrin ITGAV:ITGB3 (PubMed:27993971). Interacts with CD247/CD3 zeta, ICAM1 and CD9 at the immune synapse on T cell membrane (PubMed:23858057). Part of a GPCR-tetraspanin complex consisting at least of ADGRG1, CD81, possibly CD9, and GNA11 in which CD81 enhances the association of ADGRG1 with GNA11 (PubMed:15004227). Part of a complex composed of CD9, CD81, PTGFRN and IGSF8 (By similarity). Interacts directly with IGSF8 (PubMed:11504738). Interacts with CD53 and SCIMP (PubMed:21930792). Interacts with SAMHD1 (via its C-terminus) (PubMed:28871089). Interacts with glypican GPC3 and with the transcriptional repressor HHEX; binding to GPC3 decreases the availability of free CD81 for binding to HHEX, resulting in nuclear translocation of HHEX and transcriptional repression (By similarity). Interacts with CLDN1 (PubMed:20375010, PubMed:21516087). Interacts with CLDN6 and CLDN9 (PubMed:20375010)
