Yeast-Deletion-Library-Tools

Yeast-Deletion-Library-Tools analyzes gene sets derived from the Saccharomyces cerevisiae homozygous deletion library (approximately 4,800 diploid strains each lacking a single non-essential gene) to identify genes shared across phenotypic responses and assess functional enrichment.

Key Features:

• Library composition: Represents approximately 4,800 Saccharomyces cerevisiae diploid strains, each harboring a single deleted non-essential gene.
• Curated relational database: Stores curated information from over 677 gene sets compiled from experiments using the yeast deletion library.
• Comparative gene-set analysis: Performs comparative analysis of gene sets to pinpoint common genes among different phenotypes.
• Gene set intersection: Accepts user-uploaded gene sets and intersects them with existing data to identify shared genes.
• Functional enrichment observation: Identifies over-representation of Gene Ontology (GO) slim terms, including a noted enrichment for "cellular ion homeostasis."

Scientific Applications:

• Genome-wide identification: Enables genome-wide studies to identify genes that influence cellular responses under diverse conditions.
• Phenotype comparison: Facilitates detection of common genetic responses between chemical and physical challenges.
• Integration of external data: Allows researchers to intersect their own gene sets with the deletion-library-derived gene sets to uncover shared responses.
• Pathway and interaction discovery: Supports discovery of potential genetic interactions and pathways implicated across multiple phenotypes.

Methodology:

Stores curated gene-set information in a relational database, performs comparative gene-set analyses and set intersections with user-uploaded gene sets, and evaluates over-representation of GO slim terms such as "cellular ion homeostasis."
