Analysis of the Protein S Gene in Protein S Deficiency
2003Protein S (PS) is a 71-kDa vitamin K-dependent glycoprotein first identified in human plasma by DiScipio and colleagues in 1977 (1), a year after the discovery of the anticoagulant protein C (PC) (2,3). A few years later, Walker demonstrated that PS acts as a cofactor for activated protein C (APC) in the proteolytic inactivation of the procoagulant ...

Inhibition of Protein S by Autoantibodies in Patients with Acquired Protein S Deficiency
Thrombosis and Haemostasis, 1996SummaryThis study was undertaken to analyze antibodies to protein S (PS) in patients with an acquired PS deficiency. Plasma from symptomatic patients with acquired (n = 14) or congenital (n = 10) PS deficiency and 10 healthy donors was screened for PS antibodies by immunoblotting and for anti-phospholipid antibodies.

Protein-S-S-Glutathione Mixed Disulfides as Models of Unfolded Proteins
Biochemistry, 1994Mixed disulfides between glutathione and the reduced forms of disulfide-bonded proteins were generated and characterized to explore their suitability as models of the unfolded state of newly-synthesized secretory proteins. RNase T1 and alpha-lactalbumin were reduced and converted to mixed disulfide derivatives, named GS-RNase T1 and GS-alpha ...

S-100 is a group of closely related, small, acidic Ca2+-binding proteins (S-100a0, S-100a and S-100b, which are alpha alpha, alpha beta, and beta beta in composition, respectively). S-100 is structurally related to calmodulin and other Ca2+-binding proteins.

Palmitoylation or S-acylation is the posttranslational attachment of fatty acids to cysteine residues and is common among integral and peripheral membrane proteins. Palmitoylated proteins have been found in every eukaryotic cell type examined (yeast, insect, and vertebrate cells), as well as in viruses grown in these cells.

The transfer of a nitric oxide group to cysteine sulfhydryls on proteins, known as S-nitrosylation, is increasingly becoming recognized as a ubiquitous regulatory reaction comparable to phosphorylation. It represents a form of redox modulation in diverse tissues, including the brain.

Nanotechnology with S-Layer Proteins
2013Nanosciences are distinguished by the cross-fertilization of biology, chemistry, material sciences, and solid-state physics and hence open up a great variety of new opportunities for innovation. The technological utilization of self-assembly systems, wherein molecules spontaneously associate under equilibrium conditions into reproducible supramolecular

PROTEIN S DEFICIENCY AND ANTIBODIES TO PROTEIN S IN PATIENTS WITH BEHCET'S DISEASE
Thrombosis Research, 1997Thrombosis occurs in 20 to 30% of patients with Behçet's disease (BD). Most of the reported hemostatic abnormalities are related to the inflammatory syndrome. We have assessed the activity of antithrombin III, protein C and protein S (PS), in 30 patients with BD and in 30 healthy controls. Thrombosis antecedents were found in 16 patients.

Oral contraceptives reduce total protein S, but not free protein S.
Thrombosis Research, 1987This study is an attempt to isolate the mechanism by which oral contraceptives (OCs) despite reduced estrogen content increase the risk of thromboembolitic disease. The subjects were 10 women athletes who had used OCs containing a combination of ethinylestradiol and levonorgestrel for more than a year.

Analytical Considerations for Free Protein S Assays in Protein S Deficiency
Thrombosis and Haemostasis, 2001SummaryProtein S is an anticoagulant protein that circulates in plasma in complex with C4b-binding protein (C4BP) or in free form. Deficiency of protein S increases the risk of venous thrombosis. Measurement of free protein S, as compared to total levels, has been shown to be superior for prediction of protein S deficiency.
