background:
This gene is a member of the TIMP gene family. The proteins encoded by this gene family are natural inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix. In addition to an inhibitory role against metalloproteinases, the encoded protein has a unique role among TIMP family members in its ability to directly suppress the proliferation of endothelial cells. As a result, the encoded protein may be critical to the maintenance of tissue homeostasis by suppressing the proliferation of quiescent tissues in response to angiogenic factors, and by inhibiting protease activity in tissues undergoing remodelling of the extracellular matrix.

Function:
Complexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. Known to act on MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-13, MMP-14, MMP-15, MMP-16 and MMP-19.
Subunit:
Interacts (via the SLCterminal) with MMP2 (via the SLCterminal PEX domain); the interaction inhibits the MMP2 activity.
Subcellular Location:
Secreted.
Post-translational modifications:
The activity of TIMP2 is dependent on the presence of disulfide bonds.
Similarity:
Belongs to the protease inhibitor I35 (TIMP) family.
Contains 1 NTR domain.
