Summaries for CD81 Gene

Entrez Gene Summary for CD81 Gene

  • 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

GeneCards Summary for CD81 Gene

CD81 (CD81 Molecule) is a Protein Coding gene. Diseases associated with CD81 include Immunodeficiency, Common Variable, 6 and Common Variable Immunodeficiency. Among its related pathways are Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell and Innate Immune System. GO annotations related to this gene include MHC class II protein complex binding. An important paralog of this gene is CD9.

UniProtKB/Swiss-Prot for CD81 Gene

  • May play an important role in the regulation of lymphoma cell growth. Interacts with a 16-kDa Leu-13 protein to form a complex possibly involved in signal transduction. May act as the viral receptor for HCV.
