MotifGenie

MotifGenie identifies transcription factor binding motifs in shared chromatin immunoprecipitation sequencing (ChIP-Seq) binding sites to enable integrative motif analysis across multiple ChIP-Seq experiments.

Key Features:

• Simultaneous Analysis of Multiple Samples: Processes multiple ChIP-Seq samples concurrently to identify shared binding regions within specified genomic loci.
• Integration with Cistrome and MACS 2.0: Leverages peak regions from the Cistrome database identified by MACS 2.0 to focus analysis on high-confidence binding sites.
• Motif Search Using JASPAR: Scans shared binding regions for transcription factor motifs sourced from the JASPAR database.
• Laboratory Validation: Methods and findings have been validated through laboratory experiments in collaboration with molecular biologists.
• Implementation: Implemented in Python.

Scientific Applications:

• Regulatory Mechanism Elucidation: Identifying shared TF binding motifs across datasets to elucidate gene regulatory mechanisms.
• Cooperative Interaction Analysis: Characterizing cooperative interactions between transcription factors and chromatin-associated proteins.
• Domain Applications: Applicable to developmental biology, cancer research, and systems biology studies focused on gene regulation.

Methodology:

Implemented in Python; processes multiple ChIP-Seq samples to identify shared binding regions, uses MACS 2.0 peak regions from the Cistrome database, and scans identified regions for motifs from the JASPAR database.
