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 />

Forms a non-covalent stoichiometric complex with latent and active<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 />

inhibits MMP-2. Not available for sale in Japan.<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 />
