Protein Name: 26S proteasome non-ATPase regulatory subunit 2 homolog A

UniprotKB/SwissProt ID: Q9SIV2 (Q9SIV2)

Gene Name: RPN1A

Organism: Arabidopsis thaliana (Mouse-ear cress)

Function: 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 (PubMed:16169895). Required for optimal plant growth and stress responses (PubMed:19605416). Required for innate immunity (PubMed:22577987). Prevents JMJ27 accumulation in non-drought conditions (PubMed:34197643)
