bgafun

bgafun identifies specificity-determining residues (SDRs) within protein families to pinpoint amino acids that determine functional specificity and evolutionary divergence.

Key Features:

• Between Group Analysis (BGA): Employs Between Group Analysis to compare sequences from different functional groups and identify residues that vary significantly between those groups.
• Interoperability with Bioconductor: Integrates with the Bioconductor project and the R programming environment to leverage existing genomic and statistical packages.
• Statistical methods in R: Implements statistical analyses through Bioconductor packages in R to detect specificity-determining signals in sequence data.

Scientific Applications:

• Protein Function Analysis: Identifies SDRs to elucidate amino acids that contribute to specific protein functions within families.
• Evolutionary Studies: Detects residue differences between functional groups to inform analyses of diversification and adaptive evolution in protein families.
• Drug Design and Development: Pinpoints residues that underlie target-specific interactions relevant to rational drug design and therapeutic targeting.

Methodology:

Applies Between Group Analysis (BGA) and related statistical methods implemented in R via Bioconductor packages to compare sequence groups and identify SDRs.
