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.

Description

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].

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

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-SY5Y^G93A 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.
