Area of Science:

  • Biochemistry
  • Toxicology
  • Molecular Biology

Background:

  • Snake venoms from Viperidae and Crotalidae families contain proteins affecting blood coagulation and fibrinolysis.
  • These venom proteins exhibit high specificity, stability, and resistance to inhibitors, making them suitable for diagnostic applications.

Purpose of the Study:

  • To explore the potential of snake venom proteins as diagnostic tools.
  • To investigate the structure-function relationships of these proteins in relation to blood coagulation factors.

Main Methods:

  • Classification of snake venom proteins based on sequence similarities into families like serine proteinases, metalloproteinases, C-type lectins, disintegrins, and phospholipases A(2).
  • Analysis of the selective action of structurally similar proteins within families on different blood coagulation factors.

Main Results:

  • Snake venom proteins demonstrate specific activity against coagulation and fibrinolysis factors.
  • Structural similarities within protein families do not preclude selective targeting of different coagulation factors.
  • These proteins serve as excellent models for structure-function relationship studies.

Conclusions:

  • Snake venom proteins are valuable for developing diagnostic tests due to their specificity and stability.
  • Investigating these proteins can elucidate molecular recognition mechanisms in blood coagulation.
  • Snake venom proteins are crucial models for understanding protein structure-function dynamics.
