Proteasome Subunit Beta Type-2 (PSMB2)

Target
PSMB2
Molecular classification
Proteasome subunit, Non-catalytic protein
01

Overview

Proteasome subunit beta type-2 is a non-catalytic component of the 20S core proteasome complex, essential for regulated degradation of intracellular proteins. It contributes structurally to the active site environment within the proteasome, playing a role in protein quality control and various cellular processes like cell cycle, signal transduction, immune responses, and apoptosis. While PSMB2 itself lacks direct catalytic activity, it is crucial for proper proteasome assembly and function.
