Research AreasImmunology

Function

(Microbial infection) Specifically required for Plasmodium yoelii infectivity of hepatocytes, controlling sporozoite entry in hepatocytes via the parasitophorous vacuole and subsequent parasite differentiation to exoerythrocytic forms.

Biological Context

Subcellular Location: Cell membrane (Multi-pass membrane protein); Basolateral cell membrane (Multi-pass membrane protein)
Tissue Specificity: Expressed in oocytes (at protein level). Highly expressed in granulosa cells. Expressed in skeletal muscle mainly in endothelial cells of endomysial capillaries, in satellite cells and myoblasts (at protein level). Expressed in hepatocytes (at protein level)

Tissue Specificity

Expressed in oocytes (at protein level) (PubMed:16380109, PubMed:17290409, PubMed:23213457). Highly expressed in granulosa cells (PubMed:16380109).

Subunit

Homodimer (By similarity). 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 (By similarity). Part of a complex that includes MHC class II/HLA-DR molecules and IFITM1. Interacts with IFITM1 (By similarity). Interacts with IFITM2 and IFITM3 (PubMed:16395393). Part of integrin-tetraspanin complex composed of CD9, CD81, beta-1 and beta-2 integrins in the membrane of monocyte/macrophages (By similarity). Interacts (via the second extracellular domain) with integrin ITGAV:ITGB3 (By similarity). Interacts with CD247/CD3 zeta, ICAM1 and CD9 at the immune synapse on T cell membrane (By similarity). 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 (By similarity). Part of a complex composed of CD9, CD81, PTGFRN and IGSF8 (PubMed:23575678). Interacts directly with IGSF8 (PubMed:11673522). Interacts with CD53 and SCIMP (By similarity). Interacts with SAMHD1 (via its C-terminus) (By similarity). 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 (PubMed:23665349). Interacts with CLDN1 (By similarity). Interacts with CLDN6 and CLDN9 (By similarity)
