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 and 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.
