SIGLEC1,SN (Sialoadhesin) or CD169 is a single-pass type I transmembrane protein belonging to the sialic acid binding Ig-like lectin (SIGLEC) family in the immunoglobulin superfamily (IgSF). SIGLECs are characterized by an N-terminal Ig-like V-type (IgV)domain that mediates sialic acid binding, followed by varying numbers (2 to 17) of Ig-like C2-type (IgC2) domains in the extracellular region, a transmembrane region, and a cytoplasmic tail with intracellular immunoreceptor tyrosine-based inhibitory motifs (ITIM). They can be classified into two subgroups: Siglecs-1, -2, and -4 subgroup, and a Siglec-3/CD33-related subgroup (Siglecs-3, and -5 through -13), defined by sequence similarity and clustered gene localization. SIGLECs are widely expressed on hematopoietic cells, often in a cell-type-specific manner.  SIGLEC1 contains 16 IgC2 domains and acts as an endocytic receptor mediating clathrin dependent endocytosis.  SIGLEC1 is a macrophage-restricted adhesion molecule that mediates sialic-acid dependent binding to lymphocytes, including granulocytes, monocytes, natural killer cells, B-cells and CD8 T-cells.  SIGLEC1 preferentially binds to alpha-2,3-linked sialic acid and  SPN/CD43 on T-cells. SIGLEC1 may also play a role in hemopoiesis.  Alternative splicing produces a transcript variant encoding a soluble isoform of SIGLEC1.
