Encodes the 55 kDa regulatory subunit B alpha isoform of protein phosphatase 2A.
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. [Data from UniProt]
