PF4 - platelet factor 4 Gene
Also Known as PF-4; CXCL4; SCYB4
Species: Homo sapiens
About PF4
This gene has 2 transcripts (splice variants), 22 orthologues and 12 paralogues. Biased expression in bone marrow (RPKM 14.3), spleen (RPKM 2.7) and 1 other tissue.
Summary
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]
