Target Background

Function
(From Uniprot)
Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.
Gene References into Functions
  1. An antidote could promptly neutralize the anticoagulant effects of both FXa inhibitors. Our results suggest that drugs and aptamers with shared targets can be combined to exert more specific and potent effects than either agent alone PMID: 29863725
  2. model predicts that small vesicles promote activation of FX by the extrinsic tenase significantly better than large vesicles PMID: 28935233
  3. miR-24 was overexpressed in major trauma-induced coagulopathy (TIC) patients. The negative correlation of miR-24 with FX suggested the possibility that miR-24 might inhibit the synthesis of FX during TIC. PMID: 28694557
  4. zymogen-like factor Xa variants are conformationally dynamic and ligands such as its cofactor, factor Va, stabilize the molecule rescuing procoagulant activity. At the site of vascular injury, the variants in the presence of factor Va serve as effective prohemostatic agents. PMID: 28692575
  5. Data suggest oxidized lipid vesicles with phosphatidylserine/polyunsaturated fatty acids promote inactivation of ZPI-PZ complex or free ZPI; binding of PZ-complexed or free ZPI to oxidized vesicles mediates inactivation of ZPI (an inhibitor of FXa); blocking heparin- (anticoagulant-)binding site on ZPI interferes with binding to lipid or PZ. (ZPI = protein Z-dependent protease inhibitor; PZ = protein Z; FXa = factor Xa) PMID: 28717005

  11. This study was conducted to assess the spectrum of factor X gene mutation in Iranian patients with congenital factor X deficiency (FXD).

  16. FXa may inhibit lipopolysaccharide-mediated expression of sPLA2-IIA by suppression of cytosolic phospholipase A2 and extracellular signal-regulated kinase 1/2. PMID: 25399323
  17. Several members of a family had a c.112 G>C mutation in exon 2 of the F10 gene. Although in-silico analysis predicts this is a benign mutation, this family suggests that the amino acid substitution affects the properties of the factor X protein. PMID: 25803519
