Protein Name:
Serine/threonine-protein phosphatase PP2A-4 catalytic subunit
|
UniprotKB/SwissProt ID: P48578 (P48578)
Gene Name:
PP2A4
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: 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 a negative regulator of plant innate immunity by controlling BAK1 phosphorylation state and activation in surface-localized immune receptor complexes (PubMed:25085430)
