Area of Science:

  • Biochemistry
  • Structural Biology
  • Molecular Medicine

Background:

  • Matrix metalloproteinases (MMPs) degrade extracellular matrix, and their activity is regulated by tissue inhibitors of metalloproteinases (TIMPs).
  • Imbalances in MMP-TIMP activity are implicated in diseases such as arthritis, cancer, and metastasis.
  • Understanding the 3D structures of MMPs and TIMPs is crucial for comprehending their function and developing therapeutic strategies.

Purpose of the Study:

  • To provide a comprehensive review focusing specifically on the three-dimensional structures of MMPs and MMP-TIMP complexes.
  • To highlight the insights gained from structural data regarding protein organization, folding, and specificity.
  • To discuss the implications of structural knowledge for the design of novel therapeutic agents.

Main Methods:
