    Product Description

    The PP2A Antibody Sampler Kit provides an economical means of evaluating PP2A protein. The kit contains enough primary and secondary antibodies to perform two western blots with each antibody.

    Specificity / Sensitivity

    PP2A A Subunit (81G5) Rabbit mAb detects endogenous levels of α and β isoforms of the PP2A A subunit and does not cross-react with other PP2A subunits. PP2A B Subunit (100C1) Rabbit mAb detects endogenous levels of the α isoform of PP2A B and may recognize the β, γ, and δ isoforms of PP2A B. The antibody does not cross-react with the B', B'' or B''' families of PP2A B subunits. PP2A C Subunit (52F8) Rabbit mAb detects endogenous levels of α and β isoforms of the PP2A catalytic subunit and does not cross-react with other PP2A subunits.

    Source / Purification

    Monoclonal antibodies are produced by immunizing animals with synthetic peptides corresponding to the sequence of human PP2A A, B, or C subunit proteins.

    Background

    Protein phosphatase type 2A (PP2A) is an essential protein serine/threonine phosphatase that is conserved in all eukaryotes. PP2A is a key enzyme within various signal transduction pathways as it regulates fundamental cellular activities such as DNA replication, transcription, translation, metabolism, cell cycle progression, cell division, apoptosis and development (1-3). The core enzyme consists of catalytic C and regulatory A (or PR65) subunits, with each subunit represented by α and β isoforms (1). Additional regulatory subunits belong to four different families of unrelated proteins. Both the B (or PR55) and B' regulatory protein families contain α, β, γ and δ isoforms, with the B' family also including an ε protein. B'' family proteins include PR72, PR130, PR59 and PR48 isoforms, while striatin (PR110) and SG2NA (PR93) are both members of the B''' regulatory protein family. These B subunits competitively bind to a shared binding site on the core A subunit (1). This variable array of holoenzyme components, particularly regulatory B subunits, allows PP2A to act in a diverse set of functions. PP2A function is regulated by expression, localization, holoenzyme composition and post-translational modification. Phosphorylation of PP2A at Tyr307 by Src occurs in response to EGF or insulin and results in a substantial reduction of PP2A activity (4). Reversible methylation on the carboxyl group of Leu309 of PP2A has been observed (5,6). Methylation alters the conformation of PP2A, as well as its localization and association with B regulatory subunits (6-8).
