Source Description
UniProtActs as a cell-specific local repressor of quiescent center (QC) self-renewal by cell divisions in the primary root. Counteracts brassinosteroid (BR)-mediated cell division in the QC cells (PubMed:24981610). Regulates maternally seed size, especially before the heart stage, promoting both endothelial cells expansion and cell number in the outer integument layer of the seed coat (PubMed:23911125). Modulates the expression of genes involved in cell wall metabolism such as cell division and expansion (PubMed:23911125, PubMed:24981610). Negative regulator of flowering via the repression of FT transcription (PubMed:25343985). {ECO:0000269|PubMed:23911125, ECO:0000269|PubMed:24981610, ECO:0000269|PubMed:25343985}.

Source Description
UniProtINDUCTION: Levels follow a circadian cycle with a progressive decrease during the day time (at protein level) (PubMed:25343985). Down-regulated by brassinosteroids (BRs) in a dose- and time-dependent manner. Repressed by BES1. Auto-activation of expression (PubMed:24981610). Targeted to 26S proteasomal degradation by the CULLIN3 (CUL3)-based E3 ligases CRL3(BPMs) (PubMed:25343985). {ECO:0000269|PubMed:24981610, ECO:0000269|PubMed:25343985}.
