Assigning protein function from structure is crucial for genomics. Researchers explore computational methods focusing on functional sites, not just overall protein fold, to improve accuracy.

Area of Science:

  • Structural biology
  • Bioinformatics
  • Computational biology

Background:

  • Assigning protein function from structure is vital for structural genomics.
  • The relationship between protein fold and function is complex, necessitating focus on specific functional sites.
  • Existing computational methods for function prediction vary widely.

Purpose of the Study:

  • To review and highlight the importance of computational methods for assigning protein function based on structure.
  • To emphasize the need to analyze specific functional sites beyond global protein folds.
  • To provide an overview of diverse computational approaches used in protein function prediction.
