Sequence motifs of tissue inhibitor of metalloproteinases 2 (TIMP-2) determining progelatinase A (proMMP-2) binding and activation by membrane-type metalloproteinase 1 (MT1-MMP).
Fundamental cellular processes including angiogenesis and cell migration require a proteolytic cascade driven by interactions of membrane-type matrix metalloproteinase 1 (MT1-MMP) and progelatinase A (proMMP-2) that are dependent on the presence of tissue inhibitor of metalloproteinases 2 (TIMP-2). There are unique interactions between TIMP-2 and MT1-MMP, which we have previously defined, and h...
متن کاملTissue inhibitor of metalloproteinases-2 gene polymorphisms in chronic obstructive pulmonary disease.
Proteinase/antiproteinase imbalance is the most widely accepted theory for development of chronic obstructive pulmonary disease (COPD). Mutations of tissue inhibitor of metalloproteinases-2 (TIMP-2) that downregulate its activity may increase the activities of matrix metalloproteinases and result in the degradation of the lung matrix. Polymorphisms of the TIMP-2 gene were investigated in 88 COP...
متن کاملPeptide from the C-terminal domain of tissue inhibitor of matrix metalloproteinases-2 (TIMP-2) inhibits membrane activation of matrix metalloproteinase-2 (MMP-2).
Cellular activation of latent matrix metalloproteinase-2 (proMMP-2) requires formation of a cell membrane-associated activation complex that involves specific binding between the hemopexin domain of proMMP-2 (PEX) and the C-terminal domain of tissue inhibitor of matrix metalloproteinases-2 (C-TIMP-2). In this study, we tested the feasibility of inhibiting activation of proMMP-2 by exogenous inh...
متن کامل[Assessment of tissue inhibitor of metalloproteinases-2 (TIMP-2) in laryngeal cancer].
UNLABELLED Metalloproteinases are the proteolytic enzymes that digest components of the extracellular matrix in many physiological and pathological conditions. Their activity is regulated by their natural inhibitors: non-specific alpha2-macroglobulin and specific tissue inhibitors of metalloproteinases (TIMP). There are four TIMPs. TIMP-2 is the only enzyme that is expressed in constitutive man...
متن کاملdCas9-mediated transcriptional activation of tissue inhibitor of metalloproteinases
Selective gene activation with the dCas9 (deactivated clustered regularly interspaced short palindromic repeats [CRISPR] associated protein 9)/CRISPR targeting of a transcriptional activator effector is now well established. However, the optimal targeting of guide RNA (gRNA) for a given gene is largely a matter of trial and error. We explored the optimal targeting site for tissue inhibitor of m...
