== Function ==
[https://www.uniprot.org/uniprot/RGLG1_ARATH RGLG1_ARATH] E3 ubiquitin-protein ligase that mediates the formation of 'Lys-63'-linked ubiquitin chains. Regulates apical dominance by acting on the auxin transport proteins abundance (PubMed:17586653). Together with RGLG5, mediates the ubiquitination and subsequent proteasomal degradation of the target protein PP2CA. Functions as positive regulator of abscisic acid (ABA) signaling through ABA-dependent degradation of PP2CA, a major inhibitor of ABA signaling (PubMed:27577789). Acts as a negative regulator of drought stress response (PubMed:22095047).<ref>PMID:17586653</ref> <ref>PMID:22095047</ref> <ref>PMID:27577789</ref>
