== Disease == | |||
[https://www.uniprot.org/uniprot/FA7_HUMAN FA7_HUMAN] Defects in F7 are the cause of factor VII deficiency (FA7D) [MIM:[https://omim.org/entry/227500 227500]. A hemorrhagic disease with variable presentation. The clinical picture can be very severe, with the early occurrence of intracerebral hemorrhages or repeated hemarthroses, or, in contrast, moderate with cutaneous-mucosal hemorrhages (epistaxis, menorrhagia) or hemorrhages provoked by a surgical intervention. Finally, numerous subjects are completely asymptomatic despite very low factor VII levels.<ref>PMID:8043443</ref> <ref>PMID:2070047</ref> <ref>PMID:1634227</ref> <ref>PMID:8364544</ref> <ref>PMID:8204879</ref> <ref>PMID:7981691</ref> <ref>PMID:7974346</ref> <ref>PMID:8652821</ref> <ref>PMID:8844208</ref> <ref>PMID:8940045</ref> <ref>PMID:8883260</ref> <ref>PMID:9414278</ref> <ref>PMID:9576180</ref> <ref>PMID:9452082</ref> <ref>PMID:11091194</ref> <ref>PMID:11129332</ref> <ref>PMID:10862079</ref> <ref>PMID:12472587</ref> <ref>PMID:14717781</ref> <ref>PMID:19751712</ref> <ref>PMID:18976247</ref> <ref>PMID:19432927</ref> <ref>PMID:21206266</ref> <ref>PMID:21372693</ref> | |||
== Function == | |||
[https://www.uniprot.org/uniprot/FA7_HUMAN FA7_HUMAN] Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium. | |||

== Publication Abstract from PubMed == | |||
Selective factor VIIa-tissue factor complex (FVIIa/TF) inhibition is seen as a promising target for developing new anticoagulant drugs. Structure-based designs of the P3 moiety in the peptide mimetic factor VIIa inhibitor successfully lead to novel inhibitors with selectivity for FVIIa/TF and extrinsic coagulation the same as or even higher than those of previously reported peptide mimetic factor VIIa inhibitors. X-ray crystal structure analysis reveals that one of the novel inhibitors shows improved selectivity by forming interactions between the inhibitor and FVIIa as expected. Another of the novel inhibitors achieves improved selectivity through an unexpected hydrogen bond with Gln217, with a unique bent conformation in FVIIa/TF accompanied by conformational changes of the inhibitor and the protein. | |||
