FunctionComplexes 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.
Sequence similaritiesBelongs to the protease inhibitor I35 (TIMP) family. Contains 1 NTR domain.
Post-translational modificationsThe activity of TIMP2 is dependent on the presence of disulfide bonds.
