CC -!- FUNCTION: Receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces
CC a signal by increasing intracellular calcium ion levels and enhancing
CC MAPK1/MAPK3 activation (PubMed:8962122, PubMed:9295051,
CC PubMed:9103415). Involved in the AKT signaling cascade (By similarity).
CC Plays a role in regulation of cell migration, e.g. during wound
CC healing. Acts as a receptor for extracellular ubiquitin; leading to
CC enhanced intracellular calcium ions and reduced cellular cAMP levels.
CC Binds bacterial lipopolysaccharide (LPS) et mediates LPS-induced
CC inflammatory response, including TNF secretion by monocytes (By
CC similarity). Involved in hematopoiesis and in cardiac ventricular
CC septum formation (PubMed:9634237, PubMed:9634238, PubMed:9689100). Also
CC plays an essential role in vascularization of the gastrointestinal
CC tract, probably by regulating vascular branching and/or remodeling
CC processes in endothelial cells (PubMed:9634237). Involved in cerebellar
CC development. In the CNS, could mediate hippocampal-neuron survival
CC (PubMed:9634238, PubMed:9689100). {ECO:0000250|UniProtKB:P61073,
CC ECO:0000269|PubMed:8962122, ECO:0000269|PubMed:9103415,
CC ECO:0000269|PubMed:9295051, ECO:0000269|PubMed:9634237,
CC ECO:0000269|PubMed:9634238, ECO:0000269|PubMed:9689100}.
CC -!- SUBUNIT: Monomer. Can form homodimers. Interacts with CD164. Interacts
CC with ARRB2; the interaction is dependent on the C-terminal
CC phosphorylation of CXCR4 and allows activation of MAPK1 and MAPK3.
CC Interacts with ARR3; the interaction is dependent on the C-terminal
CC phosphorylation of CXCR4 and modulates calcium mobilization. Interacts
CC with RNF113A; the interaction, enhanced by CXCL12, promotes CXCR4
CC ubiquitination and subsequent degradation. Interacts (via the
CC cytoplasmic C-terminal) with ITCH (via the WW domains I and II); the
CC interaction, enhanced by CXCL12, promotes CXCR4 ubiquitination and
CC leads to its degradation. Interacts with extracellular ubiquitin.
CC Interacts with DBN1; this interaction is enhanced by antigenic
CC stimulation. Following LPS binding, may form a complex with GDF5,
CC HSP90AA1 and HSPA8. {ECO:0000250|UniProtKB:P61073}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:8962122,
CC ECO:0000269|PubMed:9295051}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P61073}. Cell junction {ECO:0000250}. Early
CC endosome {ECO:0000250}. Late endosome {ECO:0000250}. Lysosome
CC {ECO:0000250}. Note=In unstimulated cells, diffuse pattern on plasma
CC membrane. On agonist stimulation, colocalizes with ITCH at the plasma
CC membrane where it becomes ubiquitinated (By similarity). In the
CC presence of antigen, distributes to the immunological synapse forming
CC at the T-cell-APC contact area, where it localizes at the peripheral
CC and distal supramolecular activation cluster (SMAC) (By similarity).

CC -!- TISSUE SPECIFICITY: Lymphocytes, macrophages, neutrophils, microglial
CC cells and astrocytes. Found in spleen, thymus, bone marrow, lymph nodes
CC and, at lower levels in brain, small intestine, stomach and kidney.
CC CXCR4-A is predominant in all tissues tested. During embryonic
CC development, high levels are detected in the endothelium of developing
CC blood vessels and in many regions of the developing brain including the
CC olfactory epithelium, olfactory bulb, hippocampus, cerebellum and
CC spinal cord. {ECO:0000269|PubMed:9634237, ECO:0000269|PubMed:9634238}.
CC -!- DEVELOPMENTAL STAGE: High expression during embryonic development does
CC not seem to be associated with the differentiation of any particular
CC cell type, but is widely utilized when there is a requirement for cell
CC movement. Frequently associated with less differentiated cell types and
CC down-regulated with subsequent differentiation. Detected in sites with
CC hemopoietic potential: the yolk sac (7.5, 8.5 and 12.5 dpc) and fetal
CC liver (12.5 dpc). During gastrulation, at 7.2 to 7.8 dpc, expressed in
CC the mesoderm and the definitive endoderm. As gastrulation pattern fades
CC (8.5 dpc), expression in the mesoderm is down-regulated, while it
CC becomes predominant in neural ectoderm. Endodermal expression is
CC retained in the foregut and later in a subset of foregut derivatives,
CC including the stomach (10.5 dpc), the cystic ducts of the gall bladder
CC and the lung epithelium (12.5 dpc). In neuronal tissue: at 10.5 and
CC 12.5 dpc, expressed in the dorsal root ganglia, in the ventral mantle
CC layer of the spinal cord (or basal plates), in the hindbrain. At 14.5
CC dpc, expression more tightly confined to the neural epithelium lining
CC the ventricular space and to the external granular layer of the ventral
CC rhombic lip (the developing cerebellum). Expressed in the outpocketing
CC of the diencephalic floor at 10.5 dpc and in the developing thalamus
CC and, to a lesser extent, the developing hypothalamus. At 14.5 dpc,
CC restricted to the region where thalamus and hypothalamus meet. Detected
CC in a discrete band of cells at the edge of the olfactory bulb. In the
CC vascular system: expressed in the endothelium of numerous blood
CC vessels, but not all, at 10.5, 11.5 and 12.5 dpc, such as
CC vitelline/umbilical vessels, cardiac ventricular wall capillaries,
CC facial vessels and, at 14.5 dpc, in the vasculature of the herniated
CC gut. Expression seems to be associated with expanding vascular
CC networks. In the heart development, expressed at 10.5 dpc in the
CC precursor to the aortopulmonary (AP) septum. At 12.5 dpc, detected in
CC the AP septum at the base of the outflow tract and in the
CC atrioventricular valves. Detected in cranofacial ectoderm from 10.5 to
CC 14.5 dpc. At 10.5 and 11.5 dpc, expressed in the Rathke pouch.
CC {ECO:0000269|PubMed:10479460}.
CC -!- PTM: Phosphorylated on agonist stimulation. Rapidly phosphorylated on
CC serine and threonine residues in the C-terminal. Phosphorylation at
CC Ser-331 and Ser-332 leads to recruitment of ITCH, ubiquitination and
CC protein degradation. {ECO:0000250|UniProtKB:P61073}.
CC -!- PTM: Ubiquitinated after ligand binding, leading to its degradation.
CC Ubiquitinated by ITCH at the cell membrane on agonist stimulation. The
CC ubiquitin-dependent mechanism, endosomal sorting complex required for
CC transport (ESCRT), then targets CXCR4 for lysosomal degradation. This
CC process is dependent also on prior Ser-/Thr-phosphorylation in the C-
CC terminal of CXCR4. Also binding of ARRB1 to STAM negatively regulates
CC CXCR4 sorting to lysosomes though modulating ubiquitination of SFR5S.
CC {ECO:0000250|UniProtKB:P61073}.
CC -!- PTM: Sulfation is required for efficient binding of CXCL12/SDF-1alpha
CC and promotes its dimerization. {ECO:0000250|UniProtKB:P61073}.
CC -!- PTM: O- and N-glycosylated. N-glycosylation can mask coreceptor
CC function. The O-glycosylation chondroitin sulfate attachment does not
CC affect interaction with CXCL12/SDF-1alpha nor its coreceptor activity.
CC {ECO:0000250|UniProtKB:P61073}.
CC -!- DISRUPTION PHENOTYPE: Half of the embryos die by 17.5 dpc-18.5 dpc and
CC neonates die within a few hours. Mutants display defective vascular
CC development, cerebellar development, B-lymphopoiesis, myelopoiesis, and
CC cardiogenesis with defective formation of the large vessels supplying
CC the gastrointestinal tract. {ECO:0000269|PubMed:9634237,
CC ECO:0000269|PubMed:9634238, ECO:0000269|PubMed:9689100}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
