The Critical Assessment of protein Structure Prediction (CASP) experiment shows modest progress in protein structure prediction over a decade. CASP6 results indicate improvements in fold recognition and modeling of novel folds.

Area of Science:

  • Computational biology
  • Structural biology
  • Bioinformatics

Background:

  • The Critical Assessment of protein Structure Prediction (CASP) initiative has been instrumental in evaluating protein structure prediction methods for over ten years.
  • Assessing the accuracy and progress of computational methods for determining the three-dimensional structures of proteins is crucial for understanding biological function.

Purpose of the Study:

  • To evaluate the progress in protein structure prediction accuracy over a decade by comparing results from CASP6 with previous CASP experiments.
  • To assess the performance of different protein structure prediction approaches, including fold recognition and comparative modeling.

Main Methods:

  • Comparative analysis of protein structure models generated in CASP6 against experimental structures.

  • Evaluation of prediction accuracy across different categories, focusing on fold recognition and comparative modeling.
  • Benchmarking the performance of automated prediction servers.

    • Main Results:

    • Modest but significant progress has been observed in the fold recognition category over the CASP experiments.
    • Improvements were noted in modeling proteins with previously unknown folds, including correct topological modeling of mixed alpha/beta structures.
    • While progress in high sequence identity comparative modeling is difficult to discern, server performance in this area has advanced.

    Conclusions:

    • Cumulative progress in protein structure prediction, particularly in fold recognition, is substantial over the past decade.
    • CASP6 demonstrates continued, albeit modest, advancements in computational protein structure modeling.
    • Further development is needed, especially in high-accuracy comparative modeling, despite server performance gains.
