αS2-Casein (αS2-CN) comprises up to 10% of the casein fraction in bovine milk. The role of αS2-CN in casein micelles has not been studied in detail in part because of a lack of structural information on the molecule. Interest in the utilization of this molecule in dairy products and nutrition has been renewed by work in 3 areas: biological activity via potentially biologically active peptides, ...

Introduction: Glass ionomer cement (GIC) is a restorative material used in pediatric dentistry, which attaches to dental hard tissues and has cariostatic properties due to the ability for fluoride release. The present study aimed to assess the fluoride release and uptake capacity of two GICs in the presence of various fluoride sources. Methods: This in-vitro study was conducted on 120 disks com...

STATEMENT OF PROBLEM The casein phospho peptide-amorphous calcium phosphate with or without fluoride (CPP-ACPF and CPP-ACP respectively) are of considerably new materials which are highly recommended for prevention of dental caries. However, there is a shortage in literature on how they affect the ion concentration of saliva or dental plaque. OBJECTIVES The aim of this study was to evaluate t...

A protein kinase, able to phosphorylate casein, phosvitin, and glycogen synthase, was purified approximately 9000-fold from rabbit liver, and appeared analogous to an enzyme studied by Itarte and Huang (Itarte, E., and Huang, K.-P. (1979) J. Biol. Chem. 254, 4052-4057). This enzyme, designated here casein kinase-1, was shown to be a distinct glycogen synthase kinase and in particular to be diff...
