General description
Native calpain-1 from human erythrocytes. Ca2+-dependent cysteine proteinase with low Ca2+ requirement (half-maximal activation = 2 µM). Participates in the ATP release reaction of platelets stimulated with thrombin.
Other Notes
One unit is defined as the amount of enzyme that will hydrolyze 1 pmol Suc-LLVY-AMC in 1 min, 25°C using the Calpain Activity Assay Kit, Fluorogenic (Cat. No. QIA120). Note: 1 caseinolytic unit = 1 fluorogenic unit.

The inhibitory domains of calpastatin contain three highly conserved regions, A, B, and C, of which A and C bind calpain in a strictly Ca(2+)-dependent manner but have no inhibitory activity whereas region B inhibits calpain on its own. We

Autophagy and apoptosis, which could be induced by common stimuli, play crucial roles in development and disease. The functional relationship between autophagy and apoptosis is complex, due to the dual effects of autophagy. In the Bombyx Bm-12 cells, 20-hydroxyecdysone (20E)

Neuronal calcium sensor-1 (NCS-1) is a high-affinity, low-capacity Ca(2+)-binding protein expressed in many cell types. We previously showed that NCS-1 interacts with inositol 1,4,5-trisphosphate receptor (InsP(3)R) and modulates Ca(2+)-signaling by enhancing InsP3-dependent InsP(3)R channel activity and intracellular Ca(2+) transients.
