The antiserum was produced against synthesized peptide derived from human PP2A-alpha around the phosphorylation site of Tyr307. AA range:260-309

Phospho-PP2A-Cα (Y307) Polyclonal Antibody detects endogenous levels of PP2A-Cα protein only when phosphorylated at Y307.The name of modified sites may be influenced by many factors, such as species (the modified site was not originally found in human samples) and the change of protein sequence (the previous protein sequence is incomplete, and the protein sequence may be prolonged with the development of protein sequencing technology). When naming, we will use the "numbers" in historical reference to keep the sites consistent with the reports. The antibody binds to the following modification sequence (lowercase letters are modification sites):PDyFL

This gene encodes the phosphatase 2A catalytic subunit. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases , and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme , which is composed of a catalytic subunit and a constant regulatory subunit , that associates with a variety of regulatory subunits. This gene encodes an alpha isoform of the catalytic subunit. [provided by RefSeq , Jul 2008] ,

Catalytic activity:A phosphoprotein + H (2) O = a protein + phosphate. ,cofactor:Binds 1 iron ion per subunit. ,cofactor:Binds 1 manganese ion per subunit. ,Function:PP2A can modulate the activity of phosphorylase B kinase casein kinase 2 , mitogen-stimulated S6 kinase , and MAP-2 kinase. Can dephosphorylate SV40 large T antigen and p53. Dephosphorylates SV40 large T antigen , preferentially on serine residues 120 , 123 , 677 , and perhaps 679. The C subunit was most active , followed by the AC form , which was more active than the ABC form , and activity of all three forms was strongly stimulated by manganese , and to a lesser extent by magnesium. Dephosphorylation by the AC form , but not C or ABC form is inhibited by small T antigen. ,PTM: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. ,PTM:Reversibly methyl esterified on Leu-309. Carboxyl methylation may play a role in holoenzyme assembly. It varies during the cell cycle. ,similarity:Belongs to the PPP phosphatase family. ,similarity:Belongs to the PPP phosphatase family. PP-1 subfamily. ,subcellular location:In prometaphase cells , but not in anaphase cells , localizes at centromeres. During mitosis , also found at spindle poles. ,subunit:PP2A consists of a common heterodimeric core enzyme , composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant regulatory subunit (PR65 or subunit A) , that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55 , R3/B''/PR72/PR130/PR59 and R5/B'/B56 families) , the 48 kDa variable regulatory subunit , viral proteins , and cell signaling molecules. Interacts with NXN; the interaction is direct (By similarity) . May indirectly interact with SGOL1 , most probably through regulatory B56 subunits. ,
