MitoEdit

MitoEdit incorporates empirical base editor patterns to facilitate identification of optimal target windows and predict potential bystander edits for mtDNA base editing.

Key Features:

• Target Window Identification: MitoEdit generates a list of candidate target windows for mtDNA base editing based on user-specified target base positions and desired modifications.
• Bystander Edit Prediction: MitoEdit predicts the number and functional impact of bystander edits for each candidate target window.
• TALE Array Design: MitoEdit provides flanking nucleotide sequences designed to bind TALE (transcription activator-like effectors) array proteins.
• Sequence Input: MitoEdit accepts DNA sequences in text-based format with user-specified target base positions and desired modifications.

Scientific Applications:

• Mitochondrial Disease Modeling: MitoEdit enables optimization of mtDNA base editing to model and characterize human mitochondrial DNA mutations implicated in maternally inherited mitochondrial respiratory disorders.
• Somatic Mutation Characterization: MitoEdit supports investigation of somatic mtDNA mutations in late-onset chronic diseases and cancer through optimized base editing approaches.
• Construct Development: MitoEdit reduces the number of constructs requiring empirical testing by predicting bystander edits in silico.

Methodology:

MitoEdit incorporates empirical base editor patterns to predict bystander edits and identify optimal target windows. Users input DNA sequences in text-based format, specifying the target base position and its desired modification. The program generates candidate target windows with predicted bystander edits and functional impact, along with flanking nucleotide sequences for TALE array protein binding.
