SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ensembl_rest, requests, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides programmatic access to the Ensembl genome database, enabling researchers to query vast amounts of genomic data for over 250 species without needing to manually navigate complex web interfaces.

Core Features & Use Cases

  • Gene Information: Retrieve details for genes using symbols or Ensembl IDs.
  • Sequence Retrieval: Fetch DNA, transcript, or protein sequences.
  • Variant Analysis: Analyze genetic variations and predict their effects using VEP.
  • Comparative Genomics: Find orthologs and paralogs across species.
  • Use Case: A researcher needs to find all human genes that are orthologous to a specific mouse gene and then retrieve their protein sequences.

Quick Start

Use the ensembl-database skill to find orthologs for the human gene BRCA2 in the mouse species.

Frequently Asked Questions about ensembl-database

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I retrieve gene sequences using the Ensembl REST API?

You can retrieve gene sequences using the Ensembl REST API by querying with an Ensembl ID or gene symbol to fetch corresponding DNA, transcript, or protein sequences directly from the database. The skill handles this retrieval programmatically.

What is the best way to find orthologs for a specific gene across species?

Finding orthologs for a specific gene across species is done by querying the Ensembl database with a gene identifier to retrieve comparative genomics data and identify orthologous genes in other organisms.

Can I analyze genetic variants and predict their effects using VEP?

Yes, you can analyze genetic variants and predict their effects using VEP by submitting variant data to the Ensembl REST API, which returns comprehensive variant analysis and functional predictions.

Does the Ensembl database REST API support genomic data for non-human species?

The Ensembl database REST API supports genomic data for over 250 species, allowing you to retrieve gene information, sequences, and perform comparative genomics analysis across a wide range of non-human organisms.

How do I look up a gene by its symbol in Ensembl?

To look up a gene by its symbol in Ensembl, you query the REST API with the gene symbol to retrieve comprehensive gene details including its Ensembl ID, genomic location, and associated transcripts.

Do I need the ensembl_rest Python package to use this skill?

You need either the ensembl_rest Python package or standard HTTP requests libraries to access the Ensembl REST API, as the skill leverages these dependencies to facilitate genomic data queries.
