SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pandas, requests.

What problem does it solve?

Identifying and interpreting non-coding RNAs requires navigating fragmented databases and distinguishing evidence quality, since miRNA target predictions are noisy and most lncRNAs lack characterized functions.

Core Features & Use Cases

  • ncRNA Identification & Classification: Look up miRNAs in miRBase, lncRNAs in LNCipedia, and any ncRNA class across 40+ databases via RNAcentral and Rfam.
  • Target & Interaction Analysis: Retrieve CLIP-seq-supported miRNA-target interactions from ENCORI/starBase and investigate lncRNA mechanisms through PubMed literature.
  • Disease Association & Pathway Interpretation: Query DisGeNET for ncRNA-disease links and run pathway enrichment on validated miRNA targets via Reactome and STRING.
  • Use Case: Ask "What are the validated targets of miR-21?" to get CLIP-seq-ranked targets from ENCORI, then enrich them in Reactome to reveal miR-21's role as an oncomiR suppressing PTEN and PDCD4.

Quick Start

Ask the agent to find the experimentally validated targets of hsa-miR-21-5p and summarize its disease associations.

Frequently Asked Questions about tooluniverse-noncoding-rna

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

FAQPage Schema
How do I find validated targets of a miRNA like miR-21?

Query ENCORI/starBase with ENCORI_get_miRNA_targets using the miRNA name to get CLIP-seq-supported targets ranked by experimental evidence. For literature-validated targets, search PubMed for reporter assay or CLIP-seq studies, since computational predictions alone have high false positive rates.

How to annotate lncRNA function from a gene name?

Search LNCipedia for transcript details, sequence, and conservation, then query PubMed with the lncRNA name plus "mechanism" or "function". lncRNA mechanisms are determined experimentally, so literature evidence is essential rather than name-based inference.

What databases does this skill use for ncRNA analysis?

It uses miRBase for miRNAs, LNCipedia for lncRNAs, RNAcentral aggregating 40+ databases for all ncRNA types, Rfam for RNA families, ENCORI for miRNA-target interactions, and DisGeNET plus GTEx for disease and expression context.

Can I use TargetScan or miRTarBase predictions directly?

TargetScan has no REST API, so predictions require downloading and processing its bulk data files locally with pandas. miRTarBase blocks programmatic access, so use its bulk export or R data package, or fall back to ENCORI and PubMed searches.

What are the limitations of miRNA target prediction?

Even the best prediction algorithms have over 50% false positive rates, so only experimentally validated targets from reporter assays or CLIP-seq should be reported as findings. Predictions from TargetScan or miRanda are hypothesis-generating only.

When should I use a different skill instead of this one?

Use the RNA-seq DESeq2 skill for mRNA differential expression analysis and the CRISPR screen analysis skill for screen data. This skill covers only non-coding RNA identification, targets, and functional interpretation.
