Informations générales

Sialic acid binding Ig-like lectin 9 (Siglec-9), also known as CD329, is a member of the Siglec family of glycan-recognition proteins. Siglec-9 is a type-I transmembrane protein consisting of an N-terminal extracellular region that contains an N-terminal V-set domain and two C2-set domains, a transmembrane region, and an intracellular domain with an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an ITIM-like motif (PMID: 10801862). It is expressed quite broadly among human blood leukocytes, including monocytes, neutrophils, B cells, NK cells, and minor subsets of T cells (PMID: 32322597). Siglec-9 functions as an inhibitory immune checkpoint and can be targeted to enhance therapeutic antitumor immunity (PMID: 34155121; 37460871).
