Insights

Mutations distant from a protein's active site can alter its function, influencing evolution and drug resistance. Correlated substitutions offer a new approach for protein design, exploring these distant effects.

Area of Science:

  • Molecular Biology
  • Biochemistry
  • Evolutionary Biology

Background:

  • Mutations at non-active sites can impact protein function, as seen in drug resistance (e.g., human immunodeficiency virus 1).
  • Evolutionary analysis of nuclear receptors suggests mutations across protein domains drive functional diversification in homologous families.

Purpose of the Study:

  • To explore the potential of protein design strategies utilizing correlated substitutions.
  • To highlight how mutations distant from functional sites can be leveraged for protein engineering.

Main Methods:

  • Review of existing evidence from protein design experiments.
  • Analysis of correlation patterns in ligand-binding domains of nuclear receptors.
  • Exploration of theoretical applications of correlated substitutions in protein design.

Main Results:

  • Mutations at distant sites can significantly alter protein function.
  • Correlated substitutions provide insights into evolutionary functional diversification.
  • This approach offers a novel perspective for designing proteins with altered functions.

Conclusions:

  • Protein function is sensitive to mutations beyond canonical active sites.
  • Correlated substitution analysis is a promising avenue for future protein design.
  • Understanding distant mutation effects can inform protein engineering and drug development.

Protein Families02:47

Protein Families

Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key locations, protein...
Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

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 form...
Conserved Binding Sites01:49

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
