UniProt Comment
  • Major acute phase protein.
Biomarker applications (based on IPA annotation)
  • diagnosis
  • unspecified application
  • Advanced glycosylation endproduct receptor signaling
  • Amyloids
  • DEx/H-box helicases activate type I IFN and inflammatory cytokines production
  • Formyl peptide receptors bind formyl peptides and many other ligands
  • G alpha (i) signalling events
  • G alpha (q) signalling events
  • RIP-mediated NFkB activation via ZBP1
  • Scavenging by Class B Receptors
  • TAK1 activates NFkB by phosphorylation and activation of IKKs complex
  • TRAF6 mediated NF-kB activation

All locus annotations are based on the sentinel SNP (rs4150579) and 47 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
