Secondary Information

Presence in other biological fluids/tissue/cells golgi fractions of liver, spleen, kidney and brain
Protein Function phosphorylates caseins which is important to allow them to bind Ca2+ and for the subsequent formation of casein micelles, which remain stable in milk
Biochemical Properties cytosolic enzymes; the specific activities of casein kinase are 1433 and 30.6 pmoles/min per mg of protein in Golgi and milk respectively, giving a ratio of 47.7:1; activity inhibited by Mn2+
Significance in milk Phosphorylates any non-phosphorylated casein that is secreted and stored within the lumen of mammary alveoli
Site(s) of PTM(s)
