General annotation (Comments)

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 Ca2+ ions, phospholipids, and factor VIIIa By similarity.

Catalytic activity

Selective cleavage of Arg-|-Ile bond in factor X to form factor Xa.

Subunit structure

Heterodimer of a light chain and a heavy chain; disulfide-linked By similarity.

Subcellular location

Secreted By similarity.

Domain

Calcium binds to the gamma-carboxyglutamic acid (Gla) residues and, with stronger affinity, to another site, beyond the Gla domain By similarity.

Post-translational modification

Activated by factor XIa, which excises the activation peptide By similarity.

The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains By similarity.

Sequence similarities

Belongs to the peptidase S1 family.

Contains 2 EGF-like domains.

Contains 1 Gla (gamma-carboxy-glutamate) domain.

Contains 1 peptidase S1 domain.
