F10

Function

Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting (By similarity). Factor Xa activates pro-inflammatory and pro-fibrotic signaling pathways in a protease-activated receptor (PAR)-dependent manner (By similarity).

Post-translational modifications

The vitamin K-dependent, enzymatic carboxylation of some glutamate residues allows the modified protein to bind calcium.

N- and O-glycosylated.

Proteolytically cleaved and activated by cathepsin CTSG (By similarity). The activation peptide is cleaved by factor IXa (in the intrinsic pathway), or by factor VIIa (in the extrinsic pathway) (By similarity).

Sequence Similarities

Belongs to the peptidase S1 family.

Tissue Specificity

Plasma; synthesized in the liver.

Cellular localization
