idpr

idpr performs profiling and analysis of intrinsically disordered proteins (IDPs) and intrinsically disordered regions (IDRs) in R, enabling residue composition assessment, charge–hydropathy calculations, intrinsic disorder prediction, and integration with amino acid substitution matrices.

Key Features:

• Residue Composition Analysis: Assesses amino acid composition of protein sequences to inform disorder-related properties.
• Charge-Hydropathy Relationships: Calculates charge–hydropathy relationships to evaluate how charge distribution and hydrophobicity relate to disorder.
• Predictions of Intrinsic Disorder: Predicts regions within protein sequences that are likely to be intrinsically disordered.
• Integration with Amino Acid Substitution Matrices: Incorporates amino acid substitution matrices and calculators for evolutionary conservation and sequence-comparison analyses.
• R Implementation: Implements a suite of R functions that perform the package's analyses.

Scientific Applications:

• Protein sequence analysis: Analyze protein sequences for disorder-prone regions and composition-based properties.
• Study of IDP/IDR biological roles and interactions: Identify disorder regions to facilitate investigation of biological roles and molecular interactions.
• Structural inference: Use residue composition and charge–hydropathy measures to infer structural tendency toward disorder.
• Evolutionary and functional analysis: Combine substitution-matrix integration with disorder predictions to assess conservation and functional implications.

Methodology:

Implements R functions that perform residue composition analysis, charge–hydropathy calculations, intrinsic disorder prediction, and integration with amino acid substitution matrices and calculators.
