生物活性 | Proteasome-activating peptide 1 TFA is a peptide and a potentproteasomeactivator. Proteasome-activating peptide 1 TFA increases the chymotrypsin-like proteasomal catalytic activity and, consequently, proteolytic rates both in vitro and in culture. Proteasome-activating peptide 1 TFA prevents protein aggregation in a cellular model of amyotrophic lateral sclerosis[1]. |
体外研究 (In Vitro) | Proteasome-activating peptide 1 (TFA) (0-100 μM, 2 h) increases ChT-L catalytic activity of the 20S proteasome in a dose-dependent manner[1]. Proteasome-activating peptide 1 (TFA) (50 μM, 24 h) induces the degradation of SOD1, promotes a decrease of oxidized proteins[1]. Proteasome-activating peptide 1 (TFA) (0-100 μM) protects fibroblast and SH-SY5Y cells from oxidative stress[1]. Proteasome-activating peptide 1 (TFA) only affects the free 20S proteasomal pool[1]. Proteasome-activating peptide 1 (TFA) promotes proteasomal gate opening[1].
Cell Viability Assay Cell Line: | Human neuroblastoma (SH-SY5Y) and fibroblast cells[1] | Concentration: | 0, 50, 100 μM (in DMEM without fetal bovine serum followed by the addition of H2O2 (500 or 750 μM) or water (0.4%)) | Incubation Time: | 30 min or 2 h | Result: | Promoted long-term proteasomal activation through interaction with the 20S core particle, increased ChT-L activity of the 20S proteasome in a dose-dependent manner, and did not reduce cell fibroblast viability. |
Western Blot Analysis Cell Line: | SH-SY5YG93Acells[1] | Concentration: | 50 μM | Incubation Time: | 24 h | Result: | Increased the degradation of soluble SOD1, prevented the formation of SOD1-insoluble aggregates, and decreased the oxidized proteins in the total intracellular content. |
