Application

Calpain Inhibitor I have been used:
  • as a component of protease inhibitor cocktail for gel shift analysis
  • for treating HeLa cell cultures
  • for inhibition of 26 S proteasome in 26 S proteasome inhibition assays

Biochem/physiol Actions

Calpain Inhibitor I inhibits tumor necrosis factor-induced (TNF-induced) cleavage of Poly (ADP-ribose) polymerase (PARP) and calpastatin in apoptosis. It also inhibits oxygen/glucose deprivation (OGD) induced cleavage of caspase-12 and Bcl-xL..
Can initiate apoptosis in HL-60 cells but blocks dexamethasone-induced apoptosis in thymocytes and cycloheximide-induced apoptosis in metamyelocytes. Inhibits cyclin B degradation and arrests the cell cycle at G1/S and at meta-/anaphase. Blocks induction of nitric oxide synthase by LPS in macrophages.

The cytotoxic neutral cysteine protease inhibitor N-acetylleucylleucylnorleucinal (ALLN) inhibits cell-cycle progression in CHO cells, affecting the G1/S and metaphase-anaphase transition points, as well as S phase. Mitotic arrest induced by ALLN is associated with the inhibition of cyclin B degradation.
