Applications

Our Abpromise guarantee covers the use of ab72343 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 28, 36, 190 kDa (predicted molecular weight: 36 kDa).
IP Use at 2-5 µg/mg of lysate.

Target

  • Function
    PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase.
  • Sequence similarities
    Belongs to the PPP phosphatase family. PP-1 subfamily.
  • Post-translational
    modifications
    Reversibly 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 localization
    Cytoplasm. 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.
