== Disease ==
[https://www.uniprot.org/uniprot/FA11_HUMAN FA11_HUMAN] Defects in F11 are the cause of factor XI deficiency (FA11D) [MIM:[https://omim.org/entry/612416 612416]; also known as plasma thromboplastin antecedent deficiency or Rosenthal syndrome. It is a hemorrhagic disease characterized by reduced levels and activity of factor XI resulting in moderate bleeding symptoms, usually occurring after trauma or surgery. Patients usually do not present spontaneous bleeding but women can present with menorrhagia. Hemorrhages are usually moderate.<ref>PMID:2813350</ref> <ref>PMID:1547342</ref> <ref>PMID:7888672</ref> <ref>PMID:7669672</ref> <ref>PMID:9401068</ref> <ref>PMID:9787168</ref> <ref>PMID:10027710</ref> <ref>PMID:10606881</ref> <ref>PMID:11895778</ref> <ref>PMID:15026311</ref> <ref>PMID:15180874</ref> <ref>PMID:15953011</ref> <ref>PMID:16607084</ref> <ref>PMID:18005151</ref> <ref>PMID:21668437</ref> <ref>PMID:21457405</ref> <ref>PMID:22016685</ref> <ref>PMID:22322133</ref> <ref>PMID:21999818</ref> <ref>PMID:22159456</ref> 
== Function ==
[https://www.uniprot.org/uniprot/FA11_HUMAN FA11_HUMAN] Factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX.
<div style="background-color:#fffaf0;">
== Publication Abstract from PubMed ==
Factor XI (FXI) is a key enzyme in the coagulation pathway and an attractive target for the development of anticoagulant drugs. A small number of high-resolution crystal structures of FXIa in complex with small synthetic inhibitors have been published to date. All of these ligands have a basic P1 group and bind exclusively in the nonprime side of the active site of FXIa. Here, two structures of FXIa in complex with nonbasic inhibitors that occupy both the prime and nonprime sides of the active site are presented. These new structures could be valuable in the design and optimization of new FXIa synthethic inhibitors.
