General description

A 10 mM solution of ALLN (Cat. No. 208719) in anhydrous DMSO. Inhibitor of calpain I (Ki = 190 nM), calpain II (Ki = 220 nM), cathepsin B (Ki = 150 nM), and cathepsin L (Ki = 0.5 nM). Inhibits neutral cysteine proteases and proteasome (Ki = 6 µM). Protects against neuronal damage caused by hypoxia and ischemia. Inhibits apoptosis in thymocytes and metamyelocytes. Inhibits cell cycle progression at the G1/S border and metaphase/anaphase in CHO cells by inhibiting cyclin B degradation. Also prevents nitric oxide production by activated macrophages by interfering with transcription of the inducible nitric oxide synthase gene. Inhibits the proteolysis of IkB-α and IkB-β by the ubiquitin-proteasome complex.

Autophagy plays an important role as a cellular defense mechanism against intracellular pathogens, like viruses. Specifically, autophagy orchestrates the recruitment of specialized cargo, including viral components needed for replication, for lysosomal degradation. In addition to this primary role, the cleavage

Phospholamban (PLN) is an effective inhibitor of the sarco(endo)plasmic reticulum Ca(2+) ATPase (SERCA). Here, we examined PLN stability and degradation in primary cultured mouse neonatal cardiomyocytes (CMNCs) and mouse hearts using immunoblotting, molecular imaging, and [(35)S]methionine pulse-chase experiments, together with
