== 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.

== Publication Abstract from PubMed ==
Using an alpha-ketothiazole arginine moiety as a key recognition element, a series of small peptidomimetic molecules was designed and synthesized, and their co-crystal structures with factor XIa were studied in an effort to develop smaller, less peptidic inhibitors as antithrombotic agents.
