CSDeconv

CSDeconv applies blind deconvolution to ChIP-seq data to perform high-resolution identification of transcription factor binding sites and resolve closely spaced binding events.

Key Features:

• Blind Deconvolution Approach: Analyzes ChIP-seq signals using a blind deconvolution strategy that does not require prior knowledge of binding site locations.
• High Resolution and Accuracy: Identifies transcription factor binding sites separated by as few as 40 base pairs (bp).
• Application Across Species: Demonstrated on DosR binding in Mycobacterium tuberculosis and on GABP (GA-binding protein) data in human ChIP-seq datasets.

Scientific Applications:

• Gene regulation studies: Enables precise mapping of transcription factor binding sites to investigate regulatory mechanisms and transcriptional regulation linked to biological processes and disease.
• Analysis of densely packed regulatory regions: Resolves closely spaced binding events to facilitate detailed analysis of complex regulatory networks, exemplified by DosR in Mycobacterium tuberculosis and GABP in humans.

Methodology:

Performs blind deconvolution of ChIP-seq data without requiring prior knowledge of binding site locations to unbiasedly identify and distinguish closely spaced transcription factor binding sites.
