靶點詳情

  • 功能：
    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.
  • 基因功能參考文獻：
    1. identified the informative Chronic Liver Allograft Dysfunction (CLAD)-associated genes; CXCL4, CXCR3, EGFR, JAK2, STAT3, and Collagen IV were associated with CLAD pathogenesis; validated that CXCL4 is upstream of these informative genes in the isolated hepatic stellate cells PMID: 28053995
    2. A carboxyl-terminal fragment of this protein effects a rapid histamine release from rat peritoneal mast cells. PMID: 12383857
    3. this study identified a novel regulatory element,TME(tandem repeat of MEIS1 binding element)in the PF4 promoter and demonstrated that MEIS1/PBX complexes bind to the TME PMID: 12609849
    4. PF4 promoters are transactivated by USF1 and 2 which may play an important role in megakaryocytic gene expression PMID: 15187018
    5. The levels of PF-4 (as a platelet marker) mRNA were significantly higher in FeCl(2)-VT (2(-DeltaDeltaCT)=7.8) than in stasis-VT (2(-DeltaDeltaCT)=4.2, p<0.05). PMID: 16797058
