Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin) Specificity / Sensitivity Siglec-10 (E1D7S) Rabbit Monoclonal Antibody recognizes endogenous levels of total Siglec-10 protein. This antibody also cross-reacts with an unidentified protein of 180 kDa in some cell lines. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro673 of human Siglec-10 protein. Background Siglec-10 is a sialic acid-binding Ig-like lectin that has been shown to negatively regulate innate and adaptive immune system function (1). Siglec-10 is a type 1 transmembrane protein that has four extracellular Ig-like domains, a transmembrane region, and a cytoplasmic tail with two immunoreceptor tyrosine-based inhibitory motifs (ITIMs) (2). Siglec-10 is expressed in dendritic cells (DCs), monocytes, B cells, NK cells, and T cells (2,3). Siglec-10 interacts with CD24 to suppress immune responses to danger associated molecular patterns (DAMPs) by associating with the tyrosine phosphatase SHP-1, a negative regulator of nuclear factor-kappa B (NF-κB) (4). Siglec-10 has been shown to bind soluble CD52 leading to the impairment of phosphorylation of the T cell receptor-associated kinases Lck and Zap70 and T cell activation (3). It has been proposed that this mechanism of suppression could be involved in T cell homeostasis and the prevention of type I diabetes (3). Siglec-10 has also been identified as the leukocyte ligand for vascular adhesion protein-1 (VAP-1), which plays a key role in leukocyte trafficking (5). Lectin galactoside-binding soluble 3 binding protein (LGALS3BP), a tumor-associated immunomodulatory ligand, has also been shown to bind Siglec-10 (6).
