This is a default text for your page '''Factor XII'''. Click above on '''edit this page''' to modify. Be careful with the &lt; and &gt; signs.
You may include any references to papers as in: the use of JSmol in Proteopedia <ref>DOI 10.1002/ijch.201300024</ref> or to the article describing Jmol <ref>PMID:21638687</ref> to the rescue.


== Function ==
Coagulation '''factor XII''' (FXII) or '''Hageman factor''' is the zymogen of '''factor XIIa''' (FXIIa).  Factor XIIa , the active form of factor XII, is of crucial importance in fibrin formation<ref>PMID:22993391</ref> and initiates the procoagulant and proinflammatory contact system.


== Disease ==
== Disease ==
FXIIa has critical role in coagulation in thromboembolic diseases.


== Relevance ==
== Relevance ==
Inhibition of the FXII-driven contact system may be a promising therapeutic anticoagulation treatment strategy<ref>PMID:27834692</ref>. The choice of cyclic peptides as inhibitors of FXIIa is based on their being cell-permeable and more stable to proteolysis.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
The 3D structure of the complex between human FXIIa and a cyclic peptide inhibitor<ref>PMID:34723512</ref> shows the peptide forming <scene name='91/916250/Cv/6'>intermolecular β-sheet-like hydrogen bonds with FXIIa at two regions</scene>. Contacting residues of human FXIIa and cyclic peptide inhibitor are shown at ball-and-stick representation and colored deep sky blue and green, respectively. <scene name='91/916250/Cv/7'>Another representation</scene> of the complex between human FXIIa and a cyclic peptide inhibitor.
