Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

10.8K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Ribosome Profiling02:24

Ribosome Profiling

3.5K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Background:

  • The Quest for Orthologs (QfO) benchmark service provides standardized evaluations for orthology inference methods.
  • It facilitates the comparison of various orthology prediction tools using consistent proteome data.
  • The service is crucial for assessing the strengths and weaknesses of existing and novel orthology assignment algorithms.

Purpose of the Study:

  • To introduce a new release of the QfO benchmark service.
  • To incorporate a novel benchmark based on feature architecture similarity.
  • To present an updated set of reference proteomes for enhanced accuracy.
  • To conduct a meta-analysis of public ortholog predictions from 18 methods.

Main Methods:

  • Utilizing the Quest for Orthologs (QfO) benchmark service infrastructure.
  • Developing and implementing a new benchmark criterion: feature architecture similarity.
  • Updating reference proteomes to the latest available versions.
  • Performing a meta-analysis on existing ortholog prediction datasets.

Main Results:

  • The new QfO release features an updated benchmark and reference proteomes.
  • A meta-analysis revealed relationships between 18 orthology assignment methods regarding predictions and performance.
  • Identified strengths and weaknesses of different orthology inference approaches.

Conclusions:

  • The updated QfO benchmark service provides valuable resources for orthology method development.
  • The meta-analysis offers guidance for researchers in selecting appropriate orthology inference tools.
  • Results aid in the application of orthologs for comparative genomics and phylogenetic analyses.
