ensembldb

ensembldb provides transcript-centric annotation databases by interfacing with the Ensembl Perl API to access gene and transcript models and their annotations for downstream genomic analyses.

Key Features:

• Direct Integration with Ensembl: Interfaces with the Ensembl Perl API to access gene and transcript models and their annotations.
• Transcript-Centric Annotation: Stores and exposes annotations at the transcript level to support analyses of gene expression, transcriptome structure, and alternative splicing.
• Filter Framework: Implements a versatile filter framework to selectively retrieve annotations for specified entries and criteria.
• Interoperability with Bioconductor: Parallels TxDb packages from the GenomicFeatures Bioconductor project and interoperates with Bioconductor packages for integration into genomic analysis workflows.

Scientific Applications:

• Gene Expression Studies: Provides transcript-level annotations for quantification and comparative gene expression analyses.
• Transcriptome Analysis: Facilitates identification of novel transcripts and analysis of alternative splicing events.
• Functional Genomics: Supports functional studies linking transcript annotations to gene function and regulatory analyses.

Methodology:

Programmatic access via the Ensembl Perl API with efficient querying and retrieval of transcript-centric data and a filter framework for targeted annotation extraction.
