General description

Dephosphorylated casein is prepared by the action of potato acid phosphatase. It displays improved solubility and less foaming.

Application

Casein, Dephosphorylated from bovine milk has been used as a substrate in in vitro kinase assays of Arabidopsis thaliana GSK3/Shaggy like kinase, casein kinase II and NIMA (never in mitosis A)-related kinase 2 (Nek2).

Biochem/physiol Actions

Clusters of phosphoserine in casein chelate iron and reduce its bioavailability. Partial enzymatic digestion of casein unmasks phosphorylated residues to alkaline phosphatase, permitting dephosphorylation and increasing the bioavailability of iron.
Dephosphorylated casein lacks a net negative charge and is less sensitive to calcium. It is useful in food industry.

Quality

At least 70% dephosphorylated.

We report here the synthesis, the biological evaluation and the molecular modeling studies of new imidazo[1,2-a]pyridines derivatives designed as potent kinase inhibitors. This collection was obtained from 2-aminopyridines and 2-bromoacetophenone which afforded final compound in only one step. The bioactivity
Casein, Dephosphorylated, has been used in studies of modulators of circadian clocks. It has been shown that several molecules can inhibit casein kinase which results in the lenghthening of these clocks.

Casein kinases are critical in cell division and differentiation across species. A rice cDNA fragment encoding a putative casein kinase I (CKI) was identified via cDNA macroarray under brassinosteroid (BR) treatment, and a 1939-bp full-length cDNA, OsCKI1, was isolated and
