Proteasome-activating peptide 1 TFA
Based on 3 publication(s) in Google Scholar
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.

Biological Activity
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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Cell Line:SH-SY5YG93A cells[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.
