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. Interacts with SERPINC1. {ECO:0000250|UniProtKB:P00740}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P00740}.
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   -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00274}.
