Arabidopsis	At4g39740	Participates in copper and redox homeostasis.	Plants contain two SCO proteins that are differentially involved in cytochrome c oxidase function and copper and redox homeostasis.; 2011; DOI: 10.1093/jxb/err138; PMID: 21543521; https://pubmed.ncbi.nlm.nih.gov/21543521/
Arabidopsis	At3g08950	Acts as a copper chaperone, delivering copper to the Cu(A) site on the cytochrome c oxidase subunit II (COX2) (By similarity).	HCC1, the Arabidopsis homologue of the yeast mitochondrial copper chaperone SCO1, is essential for embryonic development.; 2011; DOI: 10.1093/jxb/erq269; PMID: 21041373; https://pubmed.ncbi.nlm.nih.gov/21041373/
