General description
Casein is a major milk phospho-protein and constitutes about 80% of the total protein content in milk. Bovine milk is composed of four types of casein such as, αS1, αS2, β, and κ. Casein exists as micelles in milk.
Application
Casein fluorescein isothiocyanate from bovine milk has been used:
- as a substrate for semi-quantitative analysis of protease in Arabidopsis cells
- to determine the caseinolytic activity of secreted LasB (elastase), alkaline protease and protease IV
- for determining the SpeB (cysteine protease) proteolytic activity in Streptococcus pyogenes cells
highly sensitive protease substrate
Biochem/physiol Actions
Casein micelle system is involved in the prevention of pathological calcification of mammary glands.

Bacterial ClpP is a highly conserved, cylindrical, self-compartmentalizing serine protease required for maintaining cellular proteostasis. Small molecule acyldepsipeptides (ADEPs) and activators of self-compartmentalized proteases 1 (ACP1s) cause dysregulation and activation of ClpP, leading to bacterial cell death, highlighting their potential

Clp proteases consist of a proteolytic, tetradecameric ClpP core and AAA+ Clp-ATPases. Streptomycetes, producers of a plethora of secondary metabolites, encode up to five different ClpP homologs, and the composition of their unusually complex Clp protease machinery has remained unsolved.
