Tissue Inhibitor of Metalloproteinase 1 (TIMP1) is a protein with a molecular mass of approximately 28 kDa. The protein inhibits metalloproteinases by binding to them preventing the breakdown of the extracellular matrix. This action regulates extracellular environment and tissue remodeling. TIMP1 is also known by the name Erythroid-Potentiating Activity (EPA). It is expressed in various tissues including the liver and the brain and can be found in high levels in the blood serum.
Biological function summary
TIMP1 plays several essential roles beyond inhibiting metalloproteinases. It supports cell proliferation and influences apoptosis. It is part of a larger TIMP family and does not function as part of a complex per se but interacts closely with matrix metalloproteinases (MMPs). By regulating MMP activity TIMP1 balances processes like tissue growth and inflammatory responses which are important for normal development and repair.
Pathways
TIMP1 participates in the regulation of the matrix metalloproteinase pathway impacting tissue homeostasis and repair. It closely associates with proteins such as MMP-9 and MMP-2 within this pathway. TIMP1 also plays a role in cytokine signaling pathways which influence immune responses by interacting with other signaling molecules and receptors that govern these pathways.
TIMP1's regulation of MMPs links it to cancer and cardiovascular disease progression. Overexpression of TIMP1 associates with tumor growth and metastasis where it can modulate interactions with other proteins like MMP-9 leading to altered tissue invasion and angiogenesis. Additionally TIMP1 imbalance connects to tissue fibrosis in cardiovascular disorders working in tandem with proteins such as MMP-2 which affects the structural remodeling and function of tissues within the cardiovascular system.
