FeatureExtract

FeatureExtract extracts sequence and feature annotations from GenBank-format files to provide intron/exon structures, promoter regions, gene locations with upstream and downstream context for genomic analyses.

Key Features:

• Annotation extraction: Extracts sequence and feature annotations from GenBank entries and other files in GenBank format, including intron/exon structures, promoter regions, and gene locations with upstream and downstream context.
• Feature-specific dataset generation: Produces datasets corresponding to specific features such as promoters and UTRs for downstream analysis.
• Consistent output format: Emits outputs in a consistent, machine-parseable format suitable for computational parsing.

Scientific Applications:

• Phylogenetic analysis: Enables consideration of intron placement within homologous genes to inform phylogenetic studies.
• Experimental design for UTR-targeting assays: Provides UTR coordinates and annotated elements to support design of PCR and DNA microarray experiments.
• Gene regulation studies: Supplies promoter region data to support investigations of gene regulatory mechanisms.

Methodology:

Accesses and parses annotations from GenBank entries and other GenBank-format files and leverages annotation data from sources such as GenBank and NCBI Human Genome builds to extract datasets for specific features (e.g., promoters, introns, UTRs).
