Cxcr4 Gene Summary [Rat]
Enables small molecule binding activity. Involved in several processes, including detection of stimulus involved in sensory perception of pain; endothelium development; and nervous system development. Located in endosome. Used to study pulmonary hypertension and temporal lobe epilepsy. Human ortholog(s) of this gene implicated in several diseases, including WHIM syndrome 1; bone disease (multiple); hematologic cancer (multiple); pancreatic adenocarcinoma; and prostate cancer. Orthologous to human CXCR4 (C-X-C motif chemokine receptor 4). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cxcr4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
