Matrix metalloproteinases (MMPs) are key enzymes in biological processes, regulated by tissue inhibitors (TIMPs). Understanding MMP structure is vital for developing therapies targeting diseases like arthritis and cancer.

Area of Science:

  • Biochemistry
  • Structural Biology
  • Molecular Medicine

Background:

  • Matrix metalloproteinases (MMPs) are zinc endopeptidases crucial for extracellular matrix remodeling and other biological functions.
  • MMP activity is tightly regulated by endogenous inhibitors, primarily tissue inhibitors of metalloproteinases (TIMPs).
  • Imbalances in MMP/TIMP activity are implicated in diseases such as arthritis, cancer, and metastasis.

Purpose of the Study:

  • To review the current understanding of matrix metalloproteinase (MMP) structure.
  • To highlight the importance of MMP structural knowledge for understanding their function and for therapeutic target development.

Main Methods:

  • This review synthesizes existing structural data on MMPs, including atomic structures published since 1994.

  • Focuses on the catalytic domain, interactions with inhibitors, domain organization, and protein complex formation.

    • Main Results:

    • Extensive structural information is available for MMP catalytic domains and their interactions with various inhibitors.
    • Details on MMP domain organization and complex formation with other proteins have been elucidated.
    • Structural insights reveal the molecular basis for MMP regulation and dysfunction.

    Conclusions:

    • Knowledge of MMP tertiary structures is fundamental to comprehending their diverse biological roles.
    • Structural information is critical for the rational design of MMP-targeted therapies for various diseases.
    • Continued structural studies will advance our understanding of MMPs and their therapeutic potential.
