Protein function
Encodes the 55 kDa regulatory subunit B alpha isoform of protein phosphatase 2A.
Phenotype
Single mutant: pp2a-b55 alpha single mutant is slightly early flowering under both SD and LD conditions. ( The early-flowering phenotype of
pp2a-b55 alpha single mutant is not statistically significant.)
[Heidari et al., 2013] Function:The B regulatory subunit may modulate substrate selectivity and catalytic activity, and also may direct the localization of the catalytic enzyme to a particular subcellular compartment.
