The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 55 kDa (predicted molecular weight: 55 kDa).Can be blocked with Human PPP2R5A peptide (ab22797).
FunctionThe B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment.
Tissue specificityWidely expressed with the highest expression in heart and skeletal muscle.
Sequence similaritiesBelongs to the phosphatase 2A regulatory subunit B56 family.
Post-translational modificationsPhosphorylated on serine residues.
Cellular localizationCytoplasm. Nucleus. Chromosome > centromere. From mitotic prophase to metaphase, localizes at the inner centromere between a pair of sister kinetochores. Decreased expression at the onset of anaphase.
