Short name: PF4

Family relationships

Description

Platelet factor 4, also known as CXC chemokine 4, is released during platelet aggregation [PMID: 11685038]. It neutralises the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule [PMID: 9531587]. It is chemotactic (CXCR3 as its receptor) for neutrophils and monocytes [PMID: 6945600]. It inhibits endothelial cell proliferation [PMID: 7644496].
