PPP2R5A Knockout HAP1 Cell Line

The choice depends on whether you are studying PPP2R5A (B56α)'s role as a PP2A B' regulatory subunit with established roles in c-MYC and BCL2 dephosphorylation. The Knockout line is the standard tool for asking whether B56α is required for PP2A targeting to specific substrates including c-MYC (S62 dephosphorylation/destabilization), BCL2, and others — B56α-containing PP2A holoenzymes are tumor suppressor effectors. Overexpression is useful for studying B56α in cancer contexts where it may be tumor-suppressive. For PP2A research, the EDITGENE PPP2R5A Knockout in HAP1 is highly informative — B56α is one of the most-studied B56 paralogs given its roles in oncogene dephosphorylation. Rescue with wild-type B56α is the standard specificity control. This product complements parallel B56 family knockouts for comprehensive PP2A B' regulatory subunit dissection. The knockout is valuable for studying PP2A reactivators (SMAPs, NZ-8-061) and B56α-specific PP2A substrate targeting.

Primary applications: • c-MYC dephosphorylation: phospho-c-MYC (S62) Western blot and protein stability analysis given B56α-PP2A's well-characterized role in c-MYC destabilization. • BCL2 regulation: phospho-BCL2 (S70) analysis given PP2A-B56α's role in BCL2 dephosphorylation and apoptosis sensitization. • PP2A reactivator studies: SMAPs (small molecule activators of PP2A like NZ-8-061), DT-061, and emerging PP2A activators tested for B56α-dependent effects. • Cancer phenotype assays: proliferation, apoptosis sensitivity given B56α-PP2A's tumor suppressor role. EDITGENE recommends this model for researchers investigating PP2A tumor suppressor biology, c-MYC regulation, and PP2A reactivator drug development.

Yes. PPP2R5A rescue experiments are well-established for PP2A tumor suppressor research: • Construct design: use a codon-modified PPP2R5A sequence with a small C-terminal tag (FLAG, HA). B56α has conserved B56 domain. • Substrate-targeting-deficient rescue: mutations in the B56 substrate-recruitment surface enable distinguishing scaffolding from substrate targeting functions. • c-MYC regulation rescue: phospho-c-MYC S62 and c-MYC protein stability restoration confirm B56α-PP2A tumor suppressor function. • Functional readout: rescue should restore B56α-specific PP2A substrate dephosphorylation, particularly c-MYC and BCL2. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.
