Protein phosphatase 2A (PP2A) B″-family subunits have Ca2+-binding EF-hand motifs and can bind PP2A substrates. Arabidopsis thaliana PP2A B″-family subunits are encoded by six genes, and bind a transcription factor, VIP1. VIP1 is dephosphorylated and nuclear-localized by hypo-osmotic stress. However, whether PP2A B″-family subunits mediate the VIP1 dephosphorylation is unclear. Here, we show by yeast two-hybrid and in vitro pull down assays that Arabidopsis PP2A B″-family subunits bind Arabidopsis PP2A A (scaffold) subunits.
