[https://www.uniprot.org/uniprot/FA10_HUMAN FA10_HUMAN] Defects in F10 are the cause of factor X deficiency (FA10D) [MIM:[https://omim.org/entry/227600 227600]. A hemorrhagic disease with variable presentation. Affected individuals can manifest prolonged nasal and mucosal hemorrhage, menorrhagia, hematuria, and occasionally hemarthrosis. Some patients do not have clinical bleeding diathesis.<ref>PMID:2790181</ref> <ref>PMID:1973167</ref> <ref>PMID:1985698</ref> <ref>PMID:7669671</ref> <ref>PMID:8529633</ref> <ref>PMID:7860069</ref> <ref>PMID:8845463</ref> <ref>PMID:8910490</ref> <ref>PMID:10468877</ref> <ref>PMID:10746568</ref> <ref>PMID:10739379</ref> <ref>PMID:11248282</ref> <ref>PMID:11728527</ref> <ref>PMID:12945883</ref> <ref>PMID:15650540</ref> <ref>PMID:17393015</ref> <ref>PMID:19135706</ref>

== Function ==
 +
[https://www.uniprot.org/uniprot/FA10_HUMAN FA10_HUMAN] 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.

 +
Unfractionated heparin (UFH), the standard anticoagulant for cardiopulmonary bypass (CPB) surgery, carries a risk of post-operative bleeding and is potentially harmful in patients with heparin-induced thrombocytopenia-associated antibodies. To improve the activity of an alternative anticoagulant, the RNA aptamer 11F7t, we solved X-ray crystal structures of the aptamer bound to factor Xa (FXa). The finding that 11F7t did not bind the catalytic site suggested that it could complement small-molecule FXa inhibitors. We demonstrate that combinations of 11F7t and catalytic-site FXa inhibitors enhance anticoagulation in purified reaction mixtures and plasma. Aptamer-drug combinations prevented clot formation as effectively as UFH in human blood circulated in an extracorporeal oxygenator circuit that mimicked CPB, while avoiding side effects of UFH. 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.
