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).

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). Active protein phosphatase 2A is composed of both structural (A) and catalytic (C) proteins, and its activity relies on interaction with regulatory (B) subunits. An important PP2A regulatory subunit is PP2A phosphatase activator (PTPA), also known as the PP2A activator regulatory subunit 4 (PPP2R4) (4). This PTPA regulatory protein binds ATP and has isomerase (PPIase) activity, suggesting that PP2A regulation involves a change in phosphatase conformation. The addition of ATP (and Mg2+) results in a correlated increase in both PP2A activation and PTPA isomerase activity (5). While the exact mechanism is still under consideration, evidence suggests that binding of PTPA to the PP2A A-C dimer produces a conformational change in PP2A that shifts phosphatase substrate specificity from phosphoserine to phosphotyrosine substrates (6).

Background: Protein Phosphatase 2A subunit isoform R5-δ (PPP2R5D) belongs to the R5/B'/B56 family of the regulatory subunit B of serine/threonine phosphatase 2A (1). PPP2R5D (B-δ) is structurally related to the other components of subunit B, B-α. PPP2R5D lacks the WD-40 repeats that are important for protein-protein interaction (1-2). Structural differences may contribute to distinct down stream effects (3) and directing PP2A nuclear localization (4). Current evidence suggests that in contrast to B-α, PPP2R5D modulates the TGF-β/Actividin/Nodal signaling pathways by restricting the downstream activities of the type I TGF-β receptors, ALK4, and ALK5 (3)

Background: Cytochrome c is a well conserved electron-transport protein and is part of the respiratory chain localized to mitochondrial intermembrane space (1). Upon apoptotic stimulation, cytochrome c released from mitochondria associates with procaspase-9 (47 kDa)/Apaf 1. This complex processes caspase-9 from inactive proenzyme to its active form (2). This event further triggers caspase-3 activation and eventually leads to apoptosis (3).
