Proteasome-activating peptide 1 TFA is a peptide and a potent proteasome activator. 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].
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].
