CD147(basigin、EMMPRIN、neurothelin、M6、HAb18G等)是一个跨膜糖蛋白家族,广泛表达于各种上皮细胞,但其表达在大鼠、小鼠、鸡和人等不同种属间存在很大差异性。CD147高表达于上皮来源的肿瘤细胞表面,如肺癌、乳腺癌和肝癌等。CD147抗原胞外段有2个IgSF结构域,跨膜区有一个带电谷氨酸(Glu)残基,胞内段含有40个氨基酸。CD147的结构特点提示其可能参与蛋白-蛋白相互作用。由于CD147分子的3D结构信息还没有获得,与其相互作用的分子还没有完全明确,但近来应用黏附、免疫共沉淀等实验方法,一些研究报道提示,CD147可与整合素(integrin)、环亲合素(cyclophilins)、单羧酸转运器(monocarboxylate transporter,MCT)等蛋白相互作用,而这些蛋白可能作为CD147分子的候选配体或受体,通过蛋白--蛋白相互作用,介导广泛的上皮细胞生物学功能。

CD 147 (basigin, EMMPRIN, neurothelin, M6, HAb18G, etc.), a transmembrane glycoprotein, has a broad expression pattern on various epithelial cells with some differences between species, e.g. rat, mouse, chicken and human, but is highly enriched on the surface of cancer cells of epithelial origin such as lung cancer, breast cancer and hepatoma cells. The CD147 antigen consists of two IgSF domains, a transmembrane sequence containing a charged residue (Glu) and a cytoplasmic domain of 40 residues. The particular structural features suggest that it is involved in protein-protein interactions. Although the interacting molecules are still not well known due to unavailability of the 3D structure of CD147, adhesion, coimmunoprecipitation and other studies recently suggest that several proteins, including integrins, cyclophilins, MCT, etc., interact with CD147 as its ligand or receptor candidates to mediate a wide range of cellular functions.
