Description

General description

TIMP1 (tissue inhibitor of metalloproteinase 1) is a glycoprotein and belongs to the TIMP family of endogenous MMP (matrix metalloproteinase) inhibitors. Humans contain four TIMPs. All TIMPs contain an N-terminal of 125 residues, a 65-residue C-terminal, and both these domains containing three disulfide bonds. The N-terminal domain inhibits MMPs by folding into a separate unit. Recombinant human TIMP-1 is a 20.6 kDa protein containing 184 amino acid residues.

Biochem/physiol Actions

TIMP1 functions as a poor inhibitor of MT1 (membrane type 1)-MMP, MT3-MMP, MT5-MMP and MMP-19. It inhibits ADAM10 (a disintegrin and metalloproteinase domain-containing protein 10) protein. In HUVECs, the down-regulation of TIMP1 and up-regulation of MMP-3 results in aberrant endothelium-dependent vasodilation, EC (endothelial cell) death, and endothelial interruption in a FOXO3 (forkhead box O3)-mediated manner. In patients with CAD (coronary artery disease) and acute coronary syndrome (ACS), the urine levels of this protein are elevated. This protein interacts with Bcl-2 (B cell lymphoma) protein, and induces apoptosis in lung adenocarcinoma cells. The plasma levels of this protein are increased in patients with obesity and obesity-related disorders, such as steatosis, where it participates in pathogenesis of diet-induced hepatic steatosis and glucose intolerance.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
