產(chǎn)品介紹    This gene encodes a sialoglycoprotein that is expressed on mature granulocytes and in many B cells. The encoded protein is anchored via a glycosyl phosphatidylinositol (GPI) link to the cell surface. [provided by RefSeq, Jul 2008].
Function : Modulates B-cell activation responses. Signaling could be triggered by the binding of a lectin-like ligand to the CD24 carbohydrates, and transduced by the release of second messengers derived from the GPI-anchor. Promotes AG-dependent proliferation of B-cells, and prevents their terminal differentiation into antibody-forming cells.
Subunit : Belongs to the CD24 family.
Subcellular Location : Cell membrane.
Tissue Specificity : B-cells. Expressed in a number of B-cell lines including P32/SH and Namalwa. Expressed in erythroleukemia cell and small cell lung carcinoma cell lines. Also expressed on the surface of T-cells.
Post-translational modifications : Extensively O-glycosylated.
DISEASE : Genetic variations in CD24 are associated with susceptibility to multiple sclerosis (MS). A multifactorial, inflammatory, demyelinating disease of the central nervous system. Sclerotic lesions are characterized by perivascular infiltration of monocytes and lymphocytes and appear as indurated areas in pathologic specimens (sclerosis in plaques). The pathological mechanism is regarded as an autoimmune attack of the myelin sheat, mediated by both cellular and humoral immunity. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia and bladder dysfunction. Genetic and environmental factors influence susceptibility to the disease. Note=Polymorphisms in CD24 may act as a genetic modifier for susceptibility and progression of MS in some populations, perhaps by affecting the efficiency of CD24 expression on the cell surface.
Similarity : Belongs to the CD24 family.

CD24是一種低分子質(zhì)量高度糖基化的黏附分子, 主要表達(dá)在造血系統(tǒng). zui近研究表明, 在造血系統(tǒng)腫瘤和一些器官的實體瘤表面可見CD24高表達(dá)。
近幾年很多學(xué)者認(rèn)為：CD24在前列腺癌、非小細(xì)胞肺癌、鼻咽癌、原發(fā)性肝細(xì)胞癌、膽管細(xì)胞癌、麥克爾細(xì)胞癌、神經(jīng)源性腫瘤、胰腺癌、胃癌、結(jié)腸癌、腎細(xì)胞癌、B細(xì)胞淋巴瘤、乳腺癌等腫瘤組織中表達(dá)增強, 且和腫瘤侵襲轉(zhuǎn)移、復(fù)發(fā)和預(yù)后相關(guān)。
