Arabidopsis	At3g19950	E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates.	No verified direct reference in this release
Arabidopsis	At5g64920	E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins.	The RING finger motif of photomorphogenic repressor COP1 specifically interacts with the RING-H2 motif of a novel Arabidopsis protein.; 1999; DOI: 10.1074/jbc.274.39.27674; PMID: 10488108; https://pubmed.ncbi.nlm.nih.gov/10488108/ | Biochemical evidence for ubiquitin ligase activity of the Arabidopsis COP1 interacting protein 8 (CIP8).; 2002; DOI: 10.1046/j.1365-313x.2002.01298.x; PMID: 12028569; https://pubmed.ncbi.nlm.nih.gov/12028569/
