Pf4 Gene Summary [Mouse]
Predicted to enable CXCR3 chemokine receptor binding activity; chemokine activity; and heparin binding activity. Involved in antimicrobial humoral immune response mediated by antimicrobial peptide and defense response to protozoan. Located in collagen-containing extracellular matrix. Is expressed in several structures, including blood vessel; bone marrow; central nervous system; liver; and yolk sac. Human ortholog(s) of this gene implicated in multiple myeloma. Orthologous to human PF4 (platelet factor 4) and PF4V1 (platelet factor 4 variant 1). [provided by Alliance of Genome Resources, Apr 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 mouse Pf4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- chemokine
- Small cytokines (intecrine/chemokine), interleukin-8 like
- CXCR3 chemokine receptor binding
- heparin binding domain
