| 产品介绍 | This gene encodes a CXC chemokine receptor specific for stromal cell-derived factor-1. The protein has 7 transmembrane regions and is located on the cell surface. It acts with the CD4 protein to support HIV entry into cells and is also highly expressed in breast cancer cells. Mutations in this gene have been associated with WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. Monomer. Can form dimers. Function: Receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. Acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Involved in hematopoiesis and in cardiac ventricular septum formation. Also plays an essential role in vascularization of the gastrointestinal tract, probably by regulating vascular branching and/or remodeling processes in endothelial cells. Involved in cerebellar development. In the CNS, could mediate hippocampal-neuron survival. Acts as a coreceptor (CD4 being the primary receptor) for HIV-1 X4 isolates and as a primary receptor for some HIV-2 isolates. Promotes Env-mediated fusion of the virus. Subunit: Monomer. Can form dimmers. Subcellular Location: Cell membrane; Multi-pass membrane protein. Tissue Specificity: Expressed in numerous tissues, such as peripheral blood leukocytes, spleen, thymus, spinal cord, heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, cerebellum, cerebral cortex and medulla (in microglia as well as in astrocytes), brain microvascular, coronary artery and umbilical cord endothelial cells. Isoform 1 is predominant in all tissues tested. Post-translational modifications: Phosphorylated on agonist stimulation. Rapidly phosphorylated on serine and threonine residues in the C-terminal. Phosphorylation at Ser-324 and Ser-325 leads to recruitment of ITCH, ubiquitination and protein degradation. Ubiquitinated by ITCH at the cell membrane on agonist stimulation. The ubiquitin-dependent mechanism, endosomal sorting complex required for transport (ESCRT), then targets CXCR4 for lysosomal degradation. This process is dependent also on prior Ser-/Thr-phosphorylation in the C-terminal of CXCR4. Also binding of ARRB1 to STAM negatively regulates CXCR4 sorting to lysosomes though modulating ubiquitination of SFR5S. Sulfation on Tyr-21 is required for efficient binding of CXCL12/SDF-1alpha and promotes its dimerization. O- and N-glycosylated. Asn-11 is the principal site of N-glycosylation. There appears to be very little or no glycosylation on Asn-176. N-glycosylation masks coreceptor function in both X4 and R5 laboratory-adapted and primary HIV-1 strains through inhibiting interaction with their Env glycoproteins. The O-glycosylation chondroitin sulfate attachment does not affect interaction with CXCL12/SDF-1alpha nor its coreceptor activity. DISEASE: Defects in CXCR4 are a cause of WHIM syndrome (WHIM) [MIM:193670]; also known as warts, hypogammaglobulinemia, infections and myelokathexis. WHIM syndrome is an immunodeficiency disease characterized by neutropenia, hypogammaglobulinemia and extensive human papillomavirus (HPV) infection. Despite the peripheral neutropenia, bone marrow aspirates from affected individuals contain abundant mature myeloid cells, a condition termed myelokathexis. Similarity: Belongs to the G-protein coupled receptor 1 family.

发现它是HIV感染T细胞的一种协同受体。CXCR5表达于成熟的B细胞表面。SCID鼠由于缺乏成熟的B细胞，脾脏内的CXCR5的水平大大降低。CXCR6主要表达于NKT细胞和活化的工型CD4T细胞和CD8T细胞。 2.CCR趋化因子受体 CCR／基因位于人染色体3p21，成熟分子含355个氨基酸残基，配体为MIP―l。和RAN―TE5；CC只1主要表达于单核细胞、中性粒细胞、T细胞、B细胞和嗜酸粒细胞，以及肺、肝等组织，类风湿关节炎患者的外周血和关节滑液中也检出CCRl。CCR2主要与MIP
趋化因子及其受体 趋化因子(chemokine)是一组小分子质量(8―1lkDa)蛋白的集合，是细胞因子家族中惟一作用于G蛋白偶联受体超家族的成员。它们直接参与白细胞特别是吞噬细胞和淋巴细胞的游走和活化，参与炎症反应并在其中起核心作用。趋化因子还具有其他多效性功能，如对肿瘤生长的调节，参与免疫系统、循环系统和神经系统的发育等。 迄今发现的人的趋化因子约有50种。趋化因子的序列相似性较低，但是三维空间结构存在显著的同源性。它们都是单链蛋白，拥有相同的单体
