CC -!- FUNCTION: Putative adhesion molecule that mediates sialic-acid
CC dependent binding to cells. Preferentially binds to alpha-2,3- or
CC alpha-2,6-linked sialic acid. The sialic acid recognition site may be
CC masked by cis interactions with sialic acids on the same cell surface.

CC -!- SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9Y336-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9Y336-2; Sequence=VSP_054106;
CC -!- TISSUE SPECIFICITY: Expressed by peripheral blood leukocytes
CC (neutrophils and monocytes but not eosinophils). Found in liver, fetal
CC liver, bone marrow, placenta, spleen and in lower levels in skeletal
CC muscle, fetal brain, stomach, lung, thymus, prostate, brain, mammary,
CC adrenal gland, colon, trachea, cerebellum, testis, small intestine and
CC spinal cordon.
CC -!- DOMAIN: Contains 1 copy of a cytoplasmic motif that is referred to as
CC the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is
CC involved in modulation of cellular responses. The phosphorylated ITIM
CC motif can bind the SH2 domain of several SH2-containing phosphatases.
CC -!- SIMILARITY: Belongs to the immunoglobulin superfamily. SIGLEC (sialic
CC acid binding Ig-like lectin) family. {ECO:0000305}.
