Background

Background:

RPN1a (26S proteasome regulatory subunit RPN1a) Acts as a regulatory subunit of the 26 proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins (By similarity). Required during embryogenesis and involved in innate immune response, proteasome-mediated ubiquitin-dependent protein catabolic process, protein catabolic process, regulation of cell cycle, regulation of protein catabolic process, response to salicylic acid, ubiquitin-dependent protein catabolic process.
Alternative names: 26S proteasome non-ATPase regulatory subunit 2 homolog A, AtRPN1a, 26S proteasome regulatory subunit S2 homolog A.
