PAnnBuilder

PAnnBuilder assembles and standardizes protein annotation datasets by parsing and integrating information from multiple public databases for large-scale proteomic analyses.

Key Features:

• Automated Data Assembly: Parses and integrates annotation data from 16 distinct public databases.
• Pre-built Annotation Packages: Provides 54 pre-assembled annotation packages for human, mouse, and rat, constructed as R objects or SQLite databases.
• Uniform Data Provision: Standardizes protein annotations across multiple sources to provide consistent annotation fields.
• Sequence-similarity-based Annotation: Supports annotations based on protein sequence similarity for comparative and evolutionary analyses.
• Custom Annotation Package Construction: Supports construction of custom annotation packages within the R framework.

Scientific Applications:

• Large-scale Proteomic Studies: Supplies integrated, standardized annotations to support analysis and interpretation of high-throughput proteomic datasets.
• Comparative Proteomics and Evolutionary Studies: Enables sequence-similarity-based annotations to facilitate comparative and evolutionary investigations.
• Reproducibility and Standardization: Provides consistent annotation datasets to improve reproducibility across proteomic analyses.

Methodology:

Uses an R-based framework to automate extraction, parsing, integration, and standardization of protein annotation data from 16 public databases and to assemble outputs as R objects or SQLite databases, including support for sequence-similarity-based annotations.
