iNitro-Tyr

iNitro-Tyr predicts nitrotyrosine sites in protein sequences to identify tyrosine residues susceptible to nitration and support studies of nitrotyrosine-related post-translational modification in diseases such as rheumatoid arthritis, septic shock, and coeliac disease.

Key Features:

• Prediction target: Identifies nitrotyrosine (tyrosine nitration) sites within protein sequences as a specific post-translational modification (PTM).
• Model composition: Integrates position-specific dipeptide propensity with general pseudo amino acid composition for site discrimination.
• Validation: Performance assessed using jackknife tests demonstrating improved success rate, stability, and reduced noise relative to existing methods.
• High-throughput capability: Designed for large-scale analysis of protein sequence datasets in postgenomic research.
• Adaptability: Methodology described as applicable to prediction of other PTM sites within proteins.

Scientific Applications:

• Site identification: Locating tyrosine residues susceptible to nitration in uncharacterized protein sequences.
• PTM mechanism studies: Supporting investigations into the functional and mechanistic roles of nitrotyrosine modifications.
• Translational research: Informing nitrotyrosine-based drug development, biomarker discovery, and disease-related studies.

Methodology:

The predictive model combines position-specific dipeptide propensity with general pseudo amino acid composition, and model performance is evaluated using jackknife tests.
