| Enzyme Function | FUNCTION: Seems to function only as a co-chaperone, along with CPN60, and in certain cases is essential for the discharge of biologically active proteins from CPN60 (PubMed:17178727, PubMed:23057508). Required to activate the iron superoxide dismutases (FeSOD) (PubMed:23057508). {ECO:0000269|PubMed:17178727, ECO:0000269|PubMed:23057508}.; FUNCTION: Involved in abscisic acid (ABA) signaling, independently of its co-chaperone role. Acts as negative regulator of the CHLH-WRKY40 coupled ABA signaling pathway, downstream of CHLH and upstream of WRKY40. {ECO:0000269|PubMed:23783410}. |
