Protein Name:
Serine/threonine-protein phosphatase PP2A-2 catalytic subunit
|
UniprotKB/SwissProt ID: Q07098 (Q07098)
Gene Name:
PP2A2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Dephosphorylates and activates the actin-depolymerizing factor ADF1, which, in turn, regulates actin cytoskeleton remodeling and is involved in the blue light photoreceptor PHOT2-mediated chloroplast avoidance movements (PubMed:22642987). Associates with the serine/threonine-protein phosphatase PP2A regulatory subunits A and B' to positively regulates beta-oxidation of fatty acids and protoauxins in peroxisomes by dephosphorylating peroxisomal beta-oxidation-related proteins (PubMed:25489022). Acts as a negative regulator of abscisic acid (ABA) signaling. May regulate ABA-dependent gene expression (PubMed:17617176). Involved in the light-dependent activation of nitrate reductase (PubMed:28656346)
