Recombinant Human Proteasome (prosome, macropain) Activator Subunit 3 (PA28 gamma; Ki), His-tagged

• Cat.No.: PSME3-6860H
• Product Overview: Recombinant human PSME3 protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques. MW: 31.7 kDa.

Specification

• Description: PSME3 belongs to the PA28 family. The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. PSME3 activates the trypsin-like catalytic subunit of the proteasome but inhibits the chymotrypsin-like and postglutamyl-preferring subunits.
