== 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 ==
Heterocyclic amide isosteres were incorporated into a phenylglycine-based tissue factor/factor VIIa (TF-FVIIa) inhibitor chemotype, providing potent inhibitors. An X-ray co-crystal structure of phenylimidazole 19 suggested that an imidazole nitrogen atom effectively mimics an amide carbonyl, while the phenyl ring forms key hydrophobic interactions with the S1' pocket. Exploration of phenylimidazole substitution led to the discovery of potent, selective and efficacious inhibitors of TF-FVIIa.
