CC趋化因子受体2/5抗体

This gene encodes two isoforms of a receptor for monocyte chemoattractant protein-1, a chemokine which specifically mediates monocyte chemotaxis. Monocyte chemoattractant protein-1 is involved in monocyte infiltration in inflammatory diseases such as rheumatoid arthritis as well as in the inflammatory response against tumors. The receptors encoded by this gene mediate agonist-dependent calcium mobilization and inhibition of adenylyl cyclase. This gene is located in the chemokine receptor gene cluster region. Two alternatively spliced transcript variants are expressed by the gene. [provided by RefSeq, Mar 2009].
Function : Receptor for the MCP-1, MCP-3 and MCP-4 chemokines. Transduces a signal by increasing the intracellular calcium ions level. Alternative coreceptor with CD4 for HIV-1 infection.
Subunit : Binds to HIV-1 Tat. Interacts with ARRB1.
Subcellular Location : Cell membrane; Multi-pass membrane protein.
Post-translational modifications : N-glycosylated.
Similarity : Belongs to the G-protein coupled receptor 1 family.
Database links : UniProtKB/Swiss-Prot: P41597
CCR-2是属于G蛋白偶联受体一家族，参与调节白细胞的迁移和活性作用，是细胞膜蛋白，它的变异与HIV-1抵抗有关。CCR-2不仅在宫颈癌组织中表达，而且在人其他肿瘤如白血病、淋巴瘤、乳腺癌、肾B 癌、胃癌、结肠癌、肝癌和子宫癌中均有过度表达，可作为肝癌及乳腺癌诊断的标志物。
