E3 ubiquitin-protein ligase EL5

UniProtKB accession:  Q9LRB7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Functions as an E3 ubiquitin-protein ligase in cooperation with the E2 ubiquitin conjugating enzymes UBC5A and UBC5B. Involved in root development. Required for the maintenance of cell viability after the initiation of root primordial formation. May mediate the degradation of cytotoxic proteins produced in root cells after the actions of auxin, cytokinin and jasmonic acid. Mediates 'Lys-48'-linked polyubiquitination of MBP in vitro.
