== Disease ==
[https://www.uniprot.org/uniprot/CXCR4_HUMAN CXCR4_HUMAN] Defects in CXCR4 are a cause of WHIM syndrome (WHIM) [MIM:[https://omim.org/entry/193670 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.<ref>PMID:12692554</ref> 
== Function ==
[https://www.uniprot.org/uniprot/C562_ECOLX C562_ECOLX] Electron-transport protein of unknown function.[https://www.uniprot.org/uniprot/CXCR4_HUMAN CXCR4_HUMAN] 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.<ref>PMID:8329116</ref> <ref>PMID:8234909</ref> <ref>PMID:8629022</ref> <ref>PMID:8752280</ref> <ref>PMID:8752281</ref> <ref>PMID:10074102</ref> <ref>PMID:10644702</ref> <ref>PMID:10825158</ref> <ref>PMID:17197449</ref> <ref>PMID:20048153</ref> <ref>PMID:20228059</ref> <ref>PMID:20505072</ref>
