Q16570

功能描述

非典型趋化因子受体,通过不偶联于经典配体驱动信号转导级联反应的高亲和力趋化因子结合来控制趋化因子的水平和定位,从而导致趋化因子隔离、降解或跨细胞转运。也被称为内吞受体(interceptor)或趋化因子清除受体或趋化因子诱饵受体。具有混杂的趋化因子结合谱,与CXC和CC亚家族的炎症趋化因子相互作用,但不与稳态趋化因子相互作用。作为趋化因子的受体,包括CCL2、CCL5、CCL7、CCL11、CCL13、CCL14、CCL17、CXCL5、CXCL6、IL8/CXCL8、CXCL11、GRO、RANTES、MCP-1和TARC。可能通过两种不同的机制调节趋化因子的生物利用度,从而调节白细胞募集:当在内皮细胞中表达时,它维持组织来源的趋化因子从基底侧到管腔侧的跨细胞转运及其随后向循环白细胞的呈递;当在红细胞中表达时,充当同源趋化因子的血液储库,但也充当趋化因子汇,缓冲血浆趋化因子水平的潜在激增。; FUNCTION: (微生物感染) 充当疟原虫Plasmodium vivax的受体。 {ECO:0000269|PubMed:38056460}.; FUNCTION: (微生物感染) 充当疟原虫Plasmodium knowlesi的受体。 {ECO:0000269|PubMed:28800732}.

组织特异性

Found in adult kidney, adult spleen, bone marrow and fetal liver. In particular, it is expressed along postcapillary venules throughout the body, except in the adult liver. Erythroid cells and postcapillary venule endothelium are the principle tissues expressing duffy. Fy(-A-B) individuals do not express duffy in the bone marrow, however they do, in postcapillary venule endothelium.

亚细胞定位

Early endosome. Recycling endosome. Membrane; Multi-pass membrane protein. Note=Predominantly localizes to endocytic vesicles, and upon stimulation by the ligand is internalized via caveolae. Once internalized, the ligand dissociates from the receptor, and is targeted to degradation while the receptor is recycled back to the cell membrane.
