UniProt Comment
  • Extracellular lectin functioning as a pattern-recognition receptor in innate immunity. Binds the sugar moieties of pathogen-associated molecular patterns (PAMPs) displayed on microbes and activates the lectin pathway of the complement system. May also activate monocytes through a G protein-coupled receptor, FFAR2, inducing the secretion of interleukin-8/IL-8 (PubMed:21037097). Binds preferentially to 9-O-acetylated 2-6-linked sialic acid derivatives and to various glycans containing sialic acid engaged in a 2-3 linkage.
  • Ficolins bind to repetitive carbohydrate structures on the target cell surface
  • Initial triggering of complement
  • Lectin pathway of complement activation

All locus annotations are based on the sentinel SNP (rs10858300) and 22 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.
