UniProt Comments
Functions redundantly with PP2A3, and is involved in establishing auxin gradients, apical-basal axis of polarity and root and shoot apical meristem during embryogenesis. May dephosphorylate PIN1 and regulate its subcellular distribution for polar auxin transport (PubMed:23167545). The holoenzyme composed of PP2AA1, PP2A4 and B'ZETA or B'ETA acts as negative regulator of plant innate immunity by controlling BAK1 phosphorylation state and activation in surface-localized immune receptor complexes (PubMed:25085430).
