Descrizione generale

Calpeptin inhibits the Ca2+-stimulatedcleavage of p35 to p25 by calpain. It regulates the processing of β-amyloidprecursor protein to β-amyloid (Aβ). Calpeptin alleviates neurite elongation indifferentiating PC12 cells. In platelets, it prevents Ca2+-ionophore-induceddegradation of actin binding protein and P235. It blocks the myosinlight chain phosphorylation in platelets stimulated by collagen, ionomycin, orthrombin. Calpeptin inhibits the growth of estrogen receptor positive breast cancer cells. Calpeptin is a cell permeable calpain blocker. It also blocks theactivation of T-cells in the immune system. It has been observed that calpeptininduces secondary inflammatory responses and apoptosis in muscle cells.[1]

Transglutaminase 1 (TGM1) plays an essential role in skin barrier formation by cross-linking proteins in differentiated keratinocytes. Here, we established a protocol for the antibody-dependent detection of TGM1 protein and the parallel detection of TGM activity. TGM1 immunoreactivity initially increased

Abnormal calcium homeostasis, activation of protease calpain, generation of p25 and hyperactivation of cyclin-dependent kinase 5 (Cdk5) have all been implicated in the pathogenesis of neurogenerative diseases including Alzheimer's disease. We have recently shown that extracellular cold-inducible RNA-binding protein (eCIRP)
