产品介绍 :   This gene encodes a member of the immunoglobulin superfamily. The encoded protein is a lectin-like adhesion molecule that binds glycoconjugate ligands on cell surfaces in a sialic acid-dependent manner. It is a type I transmembrane protein expressed only by a subpopulation of macrophages and is involved in mediating cell-cell interactions. Alternative splicing produces a transcript variant encoding an isoform that is soluble rather than membrane-bound; however, the full-length nature of this variant has not been determined. [provided by RefSeq, Jul 2008].

Function:

Acts as an endocytic receptor mediating clathrin dependent endocytosis. Macrophage-restricted adhesion molecule that mediates sialic-acid dependent binding to lymphocytes, including granulocytes, monocytes, natural killer cells, B-cells and CD8 T-cells. Preferentially binds to alpha-2,3-linked sialic acid. Binds to SPN/CD43 on T-cells. May play a role in hemopoiesis.

Subcellular Location:

Isoform 1: Cell membrane; Single-pass type I membrane protein. Isoform 2: Secreted.

Tissue Specificity:

Expressed by macrophages in various tissues. High levels are found in spleen, lymph node, perivascular macrophages in brain and lower levels in bone marrow, liver Kupffer cells and lamina propria of colon and lung. Also expressed by inflammatory macrophages in rheumatoid arthritis.

Similarity:

Belongs to the immunoglobulin superfamily. SIGLEC (sialic acid binding Ig-like lectin) family.

Contains 16 Ig-like C2-type (immunoglobulin-like) domains.

Contains 1 Ig-like V-type (immunoglobulin-like) domain.

CD169，又称sialoadhesin（Sn）或Siglee-1，这是一种200kDa的I型跨膜糖蛋白，由炎性巨噬细胞特异性表达，在细胞-细胞或细胞-基质的相互作用中发挥主要作用。可识别乳癌细胞的MUC1（CD227）和T细胞的CD43。CD169在脾、淋巴结、骨髓的基质巨噬细胞上表达最强，在肝、肠、肺的长驻巨噬细胞上中等表达，慢性炎组织的巨噬细胞，例如类风湿性滑膜、动脉粥样硬化性斑块，也强烈表达CD169。
