CC -!- FUNCTION: Factor IX is a vitamin K-dependent plasma protein that
CC participates in the intrinsic pathway of blood coagulation by
CC converting factor X to its active form in the presence of Ca(2+) ions,
CC phospholipids, and factor VIIIa. {ECO:0000250|UniProtKB:P00740}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Selective cleavage of Arg-|-Ile bond in factor X to form
CC factor Xa.; EC=3.4.21.22; Evidence={ECO:0000250|UniProtKB:P00740};
CC -!- SUBUNIT: Heterodimer of a light chain and a heavy chain; disulfide-
CC linked. {ECO:0000250|UniProtKB:P00740}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P00740}.
CC -!- DOMAIN: Calcium binds to the gamma-carboxyglutamic acid (Gla) residues
CC in the Gla domain. Calcium can also bind, with stronger affinity, to
CC another site beyond the Gla domain. Under physiological ion
CC concentrations, Ca(2+) is displaced by Mg(2+) from some of the
CC gammaglutamate residues in the N-terminal Gla domain. This leads to a
CC subtle conformation change that may affect the interaction with its
CC binding protein. {ECO:0000250|UniProtKB:P00741}.
CC -!- PTM: Activated by factor XIa, which excises the activation peptide. The
CC propeptide can also be removed by snake venom protease.
CC {ECO:0000250|UniProtKB:P00740}.
CC -!- PTM: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate
CC and asparagine is (R) stereospecific within EGF domains.
CC {ECO:0000250|UniProtKB:P00740}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
