Pig (Porcine) CD81 Molecule (CD81) interaction partners

  1. Molecular cloning; CD81 expression is widely diffused in spleen tissue

Mouse (Murine) CD81 Molecule (CD81) interaction partners

  1. adoptive transfer of wild-type regulatory T cells into CD81-deficient mice was sufficient to promote tumor growth and metastasis; these findings suggested that CD81 modulates adaptive and innate immune responses

  2. CD81-Rac (show AKT1 Antibodies) interaction exerts an important regulatory role on the innate and adaptive immunity against bacterial infection and suggests a role for CD81 in the development of novel therapeutic targets during infectious diseases.

  3. Plasmodium yoelii sporozoite rhoptry discharge occurs only in the presence of CD81, providing the first direct evidence for a role of CD81 during sporozoite productive invasion.

  4. In vitro myotubes lacking CD9P-1 (show PTGFRN Antibodies) or both CD9 (show CD9 Antibodies) and CD81 fuse with a higher frequency than normal myotubes

  5. Data suggest that GPC3 (show GPC3 Antibodies) down-regulates hepatocyte proliferation by binding to hedgehog (show SHH Antibodies) (HH) and down-regulating the HH signaling pathway and binding with CD81, thus making it unavailable to bind to Hhex (show HHEX Antibodies) and causing its nuclear translocation.

  6. CD81 interacts with the T cell receptor to suppress signaling.

  7. Data show that effective B cell receptor (BCR (show BCR Antibodies)) signaling requires collaboration with the coreceptor CD19 (show CD19 Antibodies) organized by the CD81-tetraspanin network.

  8. results indicate that the CD19/CD81 complex interacts with CD38 but this interaction is not required to induce proliferation in mouse B lymphocytes

  9. CD81 promotes the microvillus formation and/or extension while tetraspanin CD82 (show CD82 Antibodies) inhibits these events. In addition, CD81 enhances the outward bending of the plasma membrane while CD82 (show CD82 Antibodies) inhibits it.

  10. Self-renewing hematopoietic stem cells express CD81 during stress-induced proliferation.

Human CD81 Molecule (CD81) interaction partners

  1. The transmembrane segments of CD81 pack as two largely separated pairs of helices, capped by the large extracellular loop (EC2 (show TCF15 Antibodies)) at the outer membrane leaflet. The two pairs of helices converge at the inner leaflet to create an intramembrane pocket with additional electron density corresponding to a bound cholesterol molecule within the cavity.

  2. Results suggest that the CD81 antigen (CD81) expressed by B cells has differential effects on B cell proliferation or apoptosis according to Epstein-Barr virus (EBV) infection and the expression level of CD81.

  3. CD81 expression was lower in systemic sclerosis patients compared to controls independent of disease duration.

  4. IFI6 (show IFI6 Antibodies) inhibits HCV entry by impairing EGFR (show EGFR Antibodies) mediated CD81/CLDN1 (show CLDN1 Antibodies) interactions. This may be relevant to other virus entry processes employing EGFR (show EGFR Antibodies).

  5. These observations confirm the role of CD81 in liver-stage malaria and question that of scavenger receptor class B member 1 (show SCARB1 Antibodies).

  6. Data suggest that the intramolecular 188-196 bond restricts the intrinsic conformational dynamics of D-helix of cluster of differentiation 81 (CD81)-large extracellular loop (LEL), which is essential for hepatitis C virus entry.

  7. LDLR (show LDLR Antibodies) was not required for the degradation of CD81 by PCSK9 (show PCSK9 Antibodies), but its presence strengthened the PCSK9 (show PCSK9 Antibodies) effect.

  8. We propose that CD81 enables the maturation of CD19 (show CD19 Antibodies) and its trafficking to the membrane by regulating the exit of CD19 (show CD19 Antibodies) from the ER to the pre-Golgi compartment

  9. We demonstrate that this motif plays a role in the maturation and recycling of CD19 (show CD19 Antibodies) but in a CD81-independent manner.

  10. These data revealed the crucial role played by His490 and His621 in hepatitis C virus infection, particularly during CD81 binding in cell entry.

CD81 Antigen Profile

Antigen 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.
