Previous GeneCards Identifiers for PF4 Gene
This gene encodes a member of the CXC chemokine family. This chemokine is released from the alpha granules of activated platelets in the form of a homotetramer which has high affinity for heparin and is involved in platelet aggregation. This protein is chemotactic for numerous other cell type and also functions as an inhibitor of hematopoiesis, angiogenesis and T-cell function. The protein also exhibits antimicrobial activity against Plasmodium falciparum. [provided by RefSeq, Oct 2014]
GeneCards Summary for PF4 Gene
PF4 (Platelet Factor 4) is a Protein Coding gene. Diseases associated with PF4 include erythromelalgia and sneddon syndrome. Among its related pathways are Signaling by GPCR and Akt Signaling. GO annotations related to this gene include heparin binding and chemokine activity. An important paralog of this gene is CXCL1.
UniProtKB/Swiss-Prot for PF4 Gene
Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form.
