== 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 ==
Structure-activity relationships and binding mode of novel heterocyclic factor VIIa inhibitors will be described. In these inhibitors, a highly basic 5-amidinoindole moiety has been successfully replaced with a less basic 5-aminopyrrolo[3,2-b]pyridine scaffold.
