Protein Name:
Plant cysteine oxidase 3
|
UniprotKB/SwissProt ID: Q1G3U6 (Q1G3U6)
Gene Name:
PCO3
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Catalyzes the oxidation of N-terminal cysteine residues (N-Cys), thus preparing the protein for N-end rule pathway-mediated proteasomal degradation, upstream of the N-end rule enzymes ATE1, ATE2 and PRT6 (Probable) (PubMed:29848548). Controls the preparation of the group VII ethylene response factor (ERF-VII) proteins for degradation via the 26S proteasome N-end rule pathway (Probable) (PubMed:29848548). Acts as an oxygen sensor that controls the stability of ERF-VII proteins, which are stabilized in flooding-induced hypoxia, and regulate transcriptional adaptation to these adverse conditions (Probable) (PubMed:29848548)
