Cancer immunogenomics integrates somatic mutation data with HLA typing to predict neoantigens and understand immune editing of tumors. We present CancerImmunogenomicsEngine, a pure-Python pipeline for cancer immunogenomics analysis.

Synthetic lethality occurs when simultaneous loss of two genes is lethal while loss of either alone is tolerated, providing a therapeutic strategy to exploit cancer-specific vulnerabilities. We present SyntheticLethalityEngine, a pure-Python pipeline for synthetic lethality analysis.

Identifying cancer driver genes from the background of passenger mutations is a central challenge in cancer genomics. We present CancerDriverEngine, a pure-Python pipeline for cancer driver gene analysis.

Mutational signatures are patterns of somatic mutations reflecting the mutagenic processes active in a tumor. We present MutationalSignatureEngine, a pure-Python pipeline for mutational signature analysis.

Tumor mutational burden (TMB) and microsatellite instability (MSI) are established biomarkers for immunotherapy response. We present TumorMutationalBurdenEngine, a pure-Python pipeline for TMB/MSI analysis.

Intrinsically disordered proteins (IDPs) lack stable tertiary structure yet perform critical cellular functions, and their phase separation drives formation of membraneless organelles. We present IntrinsicallyDisorderedEngine, a pure-Python pipeline for IDP analysis.

Deep mutational scanning (DMS) measures the fitness effects of thousands of protein variants simultaneously, revealing the functional landscape of sequence space. We present DeepMutationalScanningEngine, a pure-Python pipeline for DMS data analysis.

Protein-protein interactions (PPIs) mediate virtually all cellular processes, and their disruption underlies many diseases. We present ProteinProteinInteractionEngine, a pure-Python pipeline for PPI network analysis.

Protein dynamics are essential for function, with conformational flexibility enabling catalysis, binding, and allosteric regulation. We present ProteinDynamicsEngine, a pure-Python pipeline for molecular dynamics trajectory analysis.

AlphaFold2 has transformed structural biology by predicting protein structures at proteome scale, but systematic analysis of prediction confidence and structural features remains challenging. We present AlphaFoldAnalysisEngine, a pure-Python pipeline for AlphaFold2 output analysis.
