|Application ||WB, IHC|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||35594 Da|
|Other Names||Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform, PP2A-alpha, Replication protein C, RP-C, PPP2CA|
|Target/Specificity||A synthetic phospho-peptide corresponding to residues surrounding Tyr307 of human PP2A was used as immunogen. The antibody only detects PP2A phosphorylated on Tyrosine 307. Predicted to cross-react with mouse, rat, bovine and pig, based on sequence homology.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||PP2A Antibody Phospho (pY307) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||PP2A is the major phosphatase for microtubule-associated proteins (MAPs). PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase. Cooperates with SGO2 to protect centromeric cohesin from separase-mediated cleavage in oocytes specifically during meiosis I (By similarity). Can dephosphorylate SV40 large T antigen and p53/TP53. Activates RAF1 by dephosphorylating it at 'Ser-259'.|
|Cellular Location||Cytoplasm. Nucleus. Chromosome, centromere. Cytoplasm, cytoskeleton, spindle pole. Note=In prometaphase cells, but not in anaphase cells, localizes at centromeres. During mitosis, also found at spindle poles. Centromeric localization requires the presence of SGO2 (By similarity).|

Protein phosphatase type 2A (PP2A) is a protein serine/threonine phosphatase that controls fundamental cellular processes, including transcription, translation, metabolism, cell growth, apoptosis, and varied other signal transduction pathways (1-3). PP2A is comprised of a core enzyme, which is made up of catalytic C and regulatory A (PR65) subunits, and a secondary regulatory B subunit. This B subunit contains four different protein families. In response to EGF or insulin, it has been shown that Src phosphorylates PP2A at Tyr307, thereby inactivating PP2A (4).
