Arabidopsis	At5g20720	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.	CHAPERONIN 20 mediates iron superoxide dismutase (FeSOD) activity independent of its co-chaperonin role in Arabidopsis chloroplasts.; 2013; DOI: 10.1111/j.1469-8137.2012.04369.x; PMID: 23057508; https://pubmed.ncbi.nlm.nih.gov/23057508/ | Cochaperonin CPN20 negatively regulates abscisic acid signaling in Arabidopsis.; 2013; DOI: 10.1007/s11103-013-0082-8; PMID: 23783410; https://pubmed.ncbi.nlm.nih.gov/23783410/
