MGI Phenotype FUNCTION: This gene encodes a vitamin K-dependent protein with key roles in multiple biological processes including coagulation, apoptosis and vasculogenesis. The encoded protein undergoes proteolytic processing to generate a mature protein which is secreted into the plasma. Mice lacking the encoded protein die in utero from a fulminant coagulopathy and associated hemorrhages. [provided by RefSeq, Oct 2015]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit neonatal lethality associated with thrombosis, hemorrhage, and thrombocytopenia. [provided by MGI curators]

Nature of Mutation
DNA sequencing using the SOLiD technique identified a T to A transversion at position 1711 of the Pros1 transcript in exon 13 of 15 total exons.  Three transcripts of the Pros1 gene are displayed on EnsemblThe mutated nucleotide causes a valine to glutamic acid substitution at amino acid 539 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1)..
Protein Function & Prediction
The Pros1 gene encodes a 675 amino acid protein that is a cofactor to activated protein C in the degradation of coagulation factors Va and VIIIa. It helps to prevent coagulation and stimulating fibrinolysis. Protein S contains four EGF-like domains, one gamma-carboxyglutamate domain and two laminin G-like domains (Uniprot Q08761). Mice homozygous for a knock-out allele exhibit neonatal lethality associated with thrombosis, hemorrhage, and thrombocytopenia.
The V539E change occurs in the second laminin G-like domain, and is predicted to be probably damaging by the PolyPhen program.
