MMP-8 Rabbit Polyclonal Antibody

Matrix metallopeptidase 8 (MMP8) Homo sapiens This gene encodes a member of the matrix metalloproteinase (MMP) family of proteins. These proteins are involved in the breakdown of extracellular matrix in embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Proteolysis at different sites on this protein results in multiple active forms of the enzyme with distinct N-termini. This protein functions in the degradation of type I, II and III collagens. The gene is part of a cluster of MMP genes which localize to chromosome 11q22.3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015], catalytic activity:Cleavage of interstitial collagens in the triple helical domain. Unlike EC 3.4.24.7, this enzyme cleaves type III collagen more slowly than type I., cofactor:Binds 2 zinc ions per subunit., cofactor:Binds 3 calcium ions per subunit., domain:The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme., enzyme regulation:Cannot be activated without removal of the activation peptide., function:Can degrade fibrillar type I, II, and III collagens., similarity:Belongs to the peptidase M10A family., similarity:Contains 4 hemopexin-like domains., subcellular location:Stored in intracellular granules., tissue specificity:Neutrophils.
