Tissue <strong>Inhibitor</strong>s of Matrix Metalloproteinases (TIMPs)<br />

Tissue inhibitors of metalloproteinases (TIMPs) are a<br />

family of ubiquitous, endogenous inhibitors that regulate<br />

the activation and activity of matrix metalloproteinases<br />

(MMPs). They have been shown in animal models to<br />

be capable of the inhibition of tumor cell invasion and<br />

metastasis. They may also be involved in other diseases<br />

such as arthritis and periodontal disease. TIMP-1 is<br />

a 184 amino acid glycoprotein of 28.5 kDa. TIMP-1<br />

preferentially binds and inhibits MMP-9 and MMP-<br />

1 through interaction with their catalytic domains.<br />

TIMP-2 is a 194 amino acid, non-glycosylated protein<br />

of 21 kDa with 43% and 44% homology to TIMP-1 and<br />

TIMP-3, respectively. It inhibits the activity of all active<br />

MMPs and regulates MMP-2 expression by binding to<br />

the C-terminal region of pro-MMP-2 (K d ~5 nM). As<br />

with TIMP-1, TIMP-2 has been shown to have erythroidpotentiating<br />

activity and cell growth-promoting<br />

activity. TIMP-3 is present in the eye. It is tightly bound<br />

to the extracellular matrix and has been shown to<br />

inhibit TNF-a converting enzyme (TACE). A mutation<br />

in TIMP-3 is found in Sorsby's fundus dystrophy, a<br />

dominantly-inherited form of blindness. TIMP-4 blocks<br />

the activities of several (MMPs) implicated in the<br />

arthritic cartilage erosion.<br />

MMPs. Shown to inhibit the activities of MMP- , MMP-2, MMP- 2, and<br />

transin.<br />

TIMP-2, Human, Recombinant PF021 (Tissue <strong>Inhibitor</strong> of Metalloproteinase 2)<br />

A 2 kDa (nonreduced) or a 24 kDa (reduced) protein expressed by a<br />

variety of cell types. Forms a non-covalent, stoichiometric complex<br />

TIMP-2, Mouse, Recombinant PF098 (Tissue <strong>Inhibitor</strong> of Metalloproteinase-2)<br />

A 94 amino acid non-glycosylated protein with 43% and 44%<br />

homology to TIMP- and TIMP-3, respectively. Inhibits the activity of<br />

all MMPs and regulates MMP-2 expression by binding to the C-terminal<br />

region of pro-MMP-2. TIMP-2 is constitutively produced by most cell<br />

types in culture, along with MMP-2.<br />

TIMP-3, Human, Recombinant PF095 (Tissue <strong>Inhibitor</strong> of metalloproteinase-3)<br />

Constitutively produced by many cell types. Differs from the other<br />

TIMPs in its localization to the extracellular matrix. TIMP-3 is more<br />

basic than the other TIMPs, and the basic residues are thought to help<br />

anchor TIMP-3 into the ECM.<br />
