RNAthermsw

RNAthermsw predicts locations of RNA thermometers (RNA thermosensors) within mRNA by simulating temperature-dependent secondary-structure changes to study temperature-regulated gene expression such as heat shock responses.


Key Features:

  • Direct temperature simulations: Performs direct temperature simulations to predict temperature-dependent secondary-structure changes in RNA sequences.
  • Moving-window energy minimization: Applies a moving window technique to perform successive energy minimization folding predictions across the sequence.
  • Parameterizable window size and temperature change: Accepts analysis parameters such as window size and desired temperature change for targeted detection of thermosensitive regions.
  • Dotted-figure outputs: Generates dotted figures that represent potential structural changes and highlight candidate thermosensitive segments.

Scientific Applications:

  • Discovery of RNA thermometers: Identifies candidate RNA thermometers (RNA thermosensors) within mRNA sequences.
  • Temperature-dependent gene regulation: Enables analysis of how temperature-induced structural changes affect preferential translation and gene expression.
  • Heat shock and thermal-stress studies: Supports investigation of mechanisms involved in heat shock response and other temperature-dependent regulatory pathways.

Methodology:

Analyzes input RNA sequences by applying a moving window across the sequence, performing direct temperature simulations and successive energy minimization folding predictions through iterative calculations, and producing dotted-figure representations of predicted structural changes.
