Rabbit Anti-Human MMP3 monoclonal antibody for ELISA, FC, ICC, IHC-P, IF, WB. Matrix Metalloproteinase 3 belongs to the peptidase M10A subfamily. It is secreted in its pro-protein form, and is activated by extracellular proteinase cleavage. MMP 3 is capable of binding to zinc and calcium ions, and has metallo-endopeptidase activity. The active enzyme degrades collagen, gelatin, fibronectin, and laminin. It is involved in normal cellular processes such as wound repair and tissue remodeling. In humans, the MMP 3 gene is located on chromosome 11.
