AKAP11 Knockout HAP1 Cell Line

The choice depends on whether you are studying AKAP11 (A-kinase anchor protein 11, AKAP220)'s role as a PKA scaffold and GSK3β-binding protein or modeling its breakthrough role as a bipolar disorder/schizophrenia shared risk gene. The Knockout line is the standard tool for asking whether AKAP11 is required for these processes — AKAP11 is an A-kinase anchor protein that scaffolds protein kinase A (PKA) at specific subcellular locations, and importantly binds GSK3β — the hypothesized molecular target of lithium (the principal treatment for bipolar disorder). Overexpression is useful for studying AKAP11 in heterologous expression contexts. For psychiatric disease research, the EDITGENE AKAP11 Knockout in HAP1 is a uniquely valuable tool — landmark exome sequencing studies (Palmer et al. Nature Genetics 2022) identified ⭐⭐ AKAP11 as a definitive shared risk gene for both bipolar disorder and schizophrenia, with ultra-rare protein-truncating variants conferring OR = 7.06 (P = 2.83 × 10⁻⁹) — one of the largest effect-size psychiatric risk genes; subsequent Nature Genetics 2025 (Iceland + UK Biobank) confirmed AKAP11 plus HECTD2 in bipolar disorder. Rescue with wild-type or PTV (protein-truncating) AKAP11 enables disease modeling; ⭐ GSK3β-binding-deficient rescue separates AKAP11's PKA scaffolding from GSK3β interaction. The knockout is uniquely valuable for studying psychiatric disease mechanisms, lithium pharmacology, and emerging GSK3β-axis psychiatric therapeutics — this is one of the most important recent discoveries in psychiatric genetics.

Primary applications: • Bipolar disorder modeling: rescue with patient-derived protein-truncating AKAP11 variants for genotype-function studies of ⭐⭐ AKAP11 as a bipolar disorder/schizophrenia shared risk gene (Palmer et al. Nature Genetics 2022). • Lithium pharmacology: in heterologous neural-relevant contexts, lithium effects on AKAP11-GSK3β axis analysis. • PKA scaffolding: PKA subcellular localization analysis in AKAP11-null cells. • GSK3β interaction: AKAP11-GSK3β interaction analysis given the proposed disease mechanism involving the lithium target. EDITGENE recommends this model as a uniquely valuable tool for psychiatric disease research and lithium-GSK3β mechanism studies — AKAP11 is one of the most important recent discoveries in psychiatric genetics.

Yes. AKAP11 rescue experiments are uniquely valuable for psychiatric disease research: • Construct design: use a codon-modified AKAP11 sequence with a small C-terminal tag (FLAG, HA). AKAP11 is a ~210 kDa scaffold protein with PKA-binding amphipathic helix and GSK3β-binding region — preserve all elements. • Bipolar disorder/schizophrenia mutation rescue: ⭐ patient-derived protein-truncating variants (PTVs) from the BipEx and SCHEMA studies enable disease genotype-function studies. • GSK3β-binding-deficient rescue: rescue with GSK3β-binding-region mutations separates PKA scaffolding from GSK3β interaction — uniquely useful for studying the proposed lithium-AKAP11-GSK3β axis. • PKA-binding-deficient rescue: amphipathic helix mutations disrupt PKA scaffolding. • Functional readout: rescue should restore PKA subcellular localization and GSK3β interaction. 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.
