Casein from bovine milk is a phosphoprotein. There are four main types of Casein which make up approximately 80% of the total protein in bovine milk: α-s1 Casein, α-s2 Casein, β-Casein, and κ-Casein. Casein is proposed to be the main protective constituent in milk

Biochem/physiol Actions

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.

The derivation of functional cardiomyocytes (CMs) from human embryonic stem cells (hESCs) represents a unique way of studying human cardiogenesis, including the development of CM subtypes. In this study, we investigated the development and organization of hESC-derived cardiomyocytes (hESC-CMs) and...

Effect of multi-frequency power ultrasound (MFPU) pretreatments on the degree of hydrolysis (DH) and mechanism of casein during alcalase enzymolysis was investigated. Results showed that MFPU pretreatment in tri-frequency 20/40/60 kHz mode significantly (p < 0.05) improved the DH value of casein. Variation...

The Drosophila mutant paraShu harbors a dominant, gain-of-function allele of the voltage-gated sodium channel gene, paralytic (para). The mutant flies display severe seizure-like phenotypes, including neuronal hyperexcitability, spontaneous spasms, ether-induced leg shaking, and heat-induced convulsions. We unexpectedly found that two...


Universal Protease Activity Assay: Casein as a Substrate

Proteases break peptide bonds. In the lab, it is often necessary to measure and/or compare the activity of proteases. Sigma's non-specific protease activity assay may be used as a standardized procedure to determine the activity of proteases, which is what we do during our quality control procedures.
