Summaries for TLR8 Gene

Entrez Gene Summary for TLR8 Gene

  • The protein encoded by this gene is a member of the Toll-like receptor (TLR) family which plays a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. The various TLRs exhibit different patterns of expression. This gene is predominantly expressed in lung and peripheral blood leukocytes, and lies in close proximity to another family member, TLR7, on chromosome X. [provided by RefSeq, Jul 2008]

GeneCards Summary for TLR8 Gene

TLR8 (Toll-Like Receptor 8) is a Protein Coding gene. Diseases associated with TLR8 include crimean-congo hemorrhagic fever and hemorrhagic fever. Among its related pathways are NF-KappaB Family Pathway and NF-KappaB Family Pathway. GO annotations related to this gene include RNA binding and double-stranded RNA binding. An important paralog of this gene is TLR6.

UniProtKB/Swiss-Prot for TLR8 Gene

  • Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific to microorganisms. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response.
