Overview

The framework combines sequence-based and structure-aware machine learning to connect phosphorylation sites with subcellular localization changes and downstream transcriptional regulation.

ModuleTask
Localization-Regulatory ClassifierIdentifies candidate localization-regulatory phosphosites
Localization Direction ClassifierPredicts nuclear accumulation vs. cytoplasmic redistribution
CPTAC analysisValidates predicted nuclear accumulation-associated sites

Key features

  • Integrates local sequence, central phosphosite, and AlphaFold-derived structural features
  • Two-stage prediction pipeline for regulatory potential and localization direction
  • CPTAC-based validation against tumor multi-omics target-gene regulation
  • Reproducible training, prediction, and analysis workflows with documented run settings

Highlights

  • Built a curated benchmark of transcription factor phosphosites with localization-related evidence
  • Achieved AUROC of 0.827 on a filtered held-out benchmark
  • Integrated CPTAC phosphoproteomic, proteomic, and RNA-seq data for downstream validation
