CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC   -!- TISSUE SPECIFICITY: Expressed in all tissues with cell division
CC       activities and in mature leaves. {ECO:0000269|PubMed:12427990,
CC       ECO:0000269|PubMed:16339806}.
CC   -!- DEVELOPMENTAL STAGE: Expressed during the G2-M phases of the cell
CC       cycle. {ECO:0000269|PubMed:15970679}.
