Target Species

Human

Target Name

F9

Target Full Name

Coagulation factor IX

Target Function

Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa.

Target Involvement

Hemophilia B (HEMB); Thrombophilia, X-linked, due to factor IX defect (THPH8)

Target Subcellular Location

Secreted.

Target Protein Families

Peptidase S1 family

Target Tissue Specificity

Detected in blood plasma (at protein level). Synthesized primarily in the liver and secreted in plasma.

Target Research Area

Cardiovascular

Target Background

This gene encodes vitamin K-dependent coagulation factor IX that circulates in the blood as an inactive zymogen. This factor is converted to an active form by factor XIa, which excises the activation peptide and thus generates a heavy chain and a light chain held together by one or more disulfide bonds. The role of this activated factor IX in the blood coagulation cascade is to activate factor X to its active form through interactions with Ca+2 ions, membrane phospholipids, and factor VIII. Alterations of this gene, including point mutations, insertions and deletions, cause factor IX deficiency, which is a recessive X-linked disorder, also called hemophilia B or Christmas disease. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing.
