REG-alpha, PA28alpha, PA28a, Proteasome Activator subunit-1, Proteasome Activator 28 subunit alpha.
PSME1 is a Proteasome Activator 28 subunit alpha essential for presentation of certain major histocompatibility (MHC) class I antigens. The PSME1 complex is an alternate proteasome activator which operates with no use of ubiquitin. The PSME1 complex is made out of two homologous subunits, alpha and beta, that functions in similar catalytic properties and is connected to a hexameric ring.
PSME1 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 269 amino acids (1-249a.a.) and having a molecular mass of 30.8kDa.
PSME1 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Escherichia Coli.
Sterile Filtered clear solution.
The PSME1 protein solution (0.5mg/1ml) is formulated in 20mM Tris-HCl buffer (pH8.0) 0.1M NaCl and 10% glycerol.
