In Vitro Suc-Leu-Leu-Val-Tyr-AMC (Suc-LLVY) is a membrane-permeable calpain-specific fluorogenic substrate, pteolytic hydrolysis of the peptidyl-7-amino bond liberates the highly fluorescent 7-amino-4-methylcoumarin (AMC) moiety[1]. The effectof TGF-β on hydrolysis of these substrates (e.g Suc-Leu-Leu-Val-Tyr-AMC) are assessed. Biliary epithelial H69 cells are incubated with 10, 1, 0.1, or 0 ng/mL TGF-β for 24 h. Substrate hydrolysis is then fluorometrically assessed in cytosolic extracts. Basal activity is 1.12, 8.33, and 14.52 nmol AMC/mg protein/min for suc-LLVY-AMC, z-LLE-AMC, and z-LLL-AMC hydrolysis, respectively[2].
Kinase Assay Immunoprecipitation is carried out for the two sets of samples, using the same amount of protein. The 20 S and 26 S proteasome immunoprecipitates are washed with 50 mM Hepes/KOH (pH 7.5), and 50 mM Hepes/KOH (pH 7.5) containing 2 mMATP, respectively, prior to the determination of peptidase activity using 50 μM suc-Leu- Leu-Val-Tyr-AMC as substrate in these buffers[3].
