Details
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 (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).

Similarity: Belongs to the peptidase S1 family. Contains 2 EGF-like domains. Contains 1 Gla (gamma-carboxy-glutamate) domain. Contains 1 peptidase S1 domain.

Subcellular location: Secreted (By similarity).

Subunit structure: Heterodimer of a light chain and a heavy chain; disulfide-linked (By similarity).

Sequence length: 471 AA.
