The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesIP: Use at 2-5µg/mg of lysate.
WB: 1/2000 - 1/10000. Detects bands of approximately 28, 36 and 190 kDa (predicted molecular weight: 36 kDa).
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionPP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase.
Sequence similaritiesBelongs to the PPP phosphatase family. PP-1 subfamily.
Post-translational modificationsReversibly methyl esterified on Leu-309. Carboxyl methylation may play a role in holoenzyme assembly. It varies during the cell cycle. Demethylated by PME1 (in vitro). Phosphorylation of either threonine (by autophosphorylation-activated protein kinase) or tyrosine results in inactivation of the phosphatase. Auto-dephosphorylation has been suggested as a mechanism for reactivation.
Cellular localizationCytoplasm. Nucleus. Chromosome > centromere. Cytoplasm > cytoskeleton > spindle pole. In prometaphase cells, but not in anaphase cells, localizes at centromeres. During mitosis, also found at spindle poles.
