Background
The PROS1 gene encodes Protein S (PS), a ~70 kDa vitamin-K dependent
plasma glycoprotein mainly synthesized by human hepatocytes. PS is a
non-enzymatic cofactor in the degradation of coagulation factors Va and
VIIIa and thus plays an anticoagulant role. Approximately 60%
circulates in complex with C4b-binding protein. Free PS is a mixture of
monomers and multimers. The 652 aa PS proprotein is heavily modified
with 11 carboxyglutamates, one hydroxyaspartate, disulfides and
glycosylation. Human Protein S shows 80% aa identity with mouse Protein
S.
