RNABindRPlus

RNABindRPlus predicts RNA-binding residues in proteins by integrating sequence homology-based predictions from HomPRIP with an optimized Support Vector Machine (SVM) classifier.

Key Features:

• Hybrid HomPRIP–SVM Framework: Combines HomPRIP homology-based residue prediction with SVM-based classification to enable RNA-binding site prediction across entire protein sequences, including regions lacking close homologs.
• Comprehensive Residue Coverage: Extends prediction beyond aligned homologous regions, overcoming limitations of sequence homology-only methods.
• Benchmark-Validated Performance: Demonstrates improved Matthews Correlation Coefficients (MCC) on RB44 and RB111 datasets, achieving MCC values of 0.55 and 0.37, respectively.

Scientific Applications:

• Protein–RNA Interaction Analysis: Identifies RNA-binding interfaces to support structural biology, functional genomics, and structure-based drug design targeting RNA-binding proteins.

Methodology:

RNABindRPlus integrates HomPRIP sequence homology-based predictions with an optimized Support Vector Machine classifier to generate residue-level RNA-binding predictions, improving coverage and precision–recall performance across diverse protein datasets.
