Abstract
Background: Mammary tumors are the second most common tumors (after skin tumors) in female dogs (Canis lupus familiaris). Tissue Inhibitor of Metlloproteinases-3 (TIMP-3) is a matrix associated endogenous inhibitor of Matrix Metalloproteinases (MMPs). Cancer metastasis occurs as a result of imbalance between MMPs and TIMPs. TIMP-3 is involved significantly in regulation of MMPs as well as progression of canine mammary tumor.
Objective: The present study was conducted to identify the structural and functional relationship between TIMP-3 and MMP which can aid in identifying the role of these proteins in canine mammary tumor.
Methods: Molecular characterization of TIMP-3 protein was done by molecular biology techniques such as gene cloning and sequencing. The homology based model of TIMP-3 protein was created and verified with a variety of available computational techniques as well as molecular dynamics simulation.
Results: The results indicated that predicted TIMP-3 protein structure of Canis lupus familiaris was reliable and more stable. The docking of TIMP-3 protein with MMP-2 and MMP-9 represents conformational structure of these two proteins which interact with each other but if misled canresult in the progression of tumor in canine.
Conclusions: The three dimensional structure of TIMP-3 was generated and its interactions with MMP-2 and MMP-9, demonstrates the role of key binding residues. Until now, no structural details were available for canine TIMP-3 proteins, hence this study will broaden the horizon towards understanding the structural and functional aspects of this proteins in canine.
Keywords: Matrixmetalloproteinases, tissue inhibitors of metalloproteinases, molecular dynamic simulation, docking.
