primaryTranscriptAnnotation

primaryTranscriptAnnotation infers primary transcript boundaries from genomic run-on data to generate data-driven annotations that improve inference of transcriptional start and termination sites and quantification of nascent transcription, including RNA polymerase pause indices.

Key Features:

• Data-Driven Annotation: Generates primary transcript annotations from genomic run-on data to infer transcriptional start and termination sites.
• Integration of Existing Annotations: Annotates de novo identified transcriptional units (e.g., genes and enhancers) using existing gene annotations.
• Enhanced Sensitivity and Accuracy: Increases sensitivity for detecting differentially expressed transcripts and improves quantification of RNA polymerase pause indices.
• Application Across Cell Types: Accounts for transcript isoform variation in start and end coordinates across different cell types.

Scientific Applications:

• Transcriptional Mechanisms: Elucidates transcriptional mechanisms by providing accurate primary transcript boundaries for nascent transcription analyses.
• Gene Regulatory Networks: Supports investigation of gene regulatory networks by integrating data-driven annotations with de novo identified transcriptional units.
• Early Adipogenesis Studies: Has been applied to study transcriptional mechanisms and gene regulatory networks during early adipogenesis.

Methodology:

Uses genomic run-on data to infer primary transcript coordinates and refines existing annotations to enhance detection and quantification of transcriptional activity.
