ProminTools

ProminTools analyzes protein sequences implicated in biomineralization to compare two protein sets and identify global properties, motif content, and composition biases (including low sequence complexity and biased amino acid composition) that may indicate functional roles.

Key Features:

• Comparative sequence analysis: Compares two sets of protein sequences to identify distinctive global properties and motif content while accounting for low sequence complexity and biased amino acid composition.
• Statistical analysis against background proteome: Performs robust statistical tests relative to the background proteome to identify patterns and motifs that are significantly enriched or depleted.
• Output formats and scripting: Produces data tables and graphical summaries embedded in an HTML file and provides an R script for customizable downstream visualization.

Scientific Applications:

• Biomineralization proteomics: Analysis of proteins with unknown functions implicated in biomineralization to generate hypotheses about their roles.
• Shell matrix proteome analysis: Comparative study of shell matrix proteomes such as those from Lottia gigantea to elucidate mechanisms of biomineral formation.
• Biomaterials and fitness studies: Supporting discovery of biomineral-inspired materials and investigations into the fitness implications of biominerals across organisms.

Methodology:

Conducts comparative analysis of two protein sequence sets to identify global properties and motifs and assesses statistical significance of observed patterns relative to the broader/background proteome.
