Application

MMP-1 (matrix metalloproteinase 1) human has been used to study effect of NF (nuclear factor)κB-mediated expression of MMP-1 in breast cancer spheroids.

Biochem/physiol Actions

Matrix metalloproteinases (MMPs) enzymes play a central role in the maintenance and remodeling of the extracellular matrix. Elevated expression of their activity, caused either by up-regulation of their expression or down-regulation of their cognate inhibitors, has been implicated in various degenerative disorders, including arthritis, cardiovascular disease, skeletal growth-plate disorders, and cancer metastasis. MMP-1 is a secreted collagenase with specificity toward Type I, II, III, VII, and X collagens, aggrecan, serpins, and α2-macroglobulin. It is overexpressed in lumbar intervertebral disc degeneration (IDD). It might also be associated with osteoarthritis. MMP-1 is linked with Jjuvenile idiopathic arthritis. Genetic variations in MMP-1 can affect the susceptibility and severity of this disease.

General description

Matrix metalloproteinases (MMPs) are a family of endoproteases that require zinc and calcium for expressing catalytic activity. MMP-1 is expressed in various cells, including fibroblasts, keratinocytes, chondrocytes, monocytes and macrophages, hepatocytes and many tumor cells. The gene is mapped to human chromosome 11q22. Recombinant human MMP-1 is a 42.7kDa protein containing the entire catalytic N-terminal domain and the C-terminal domain which is involved in substrate specificity and in binding TIMP-1 (tissue inhibitor of metalloproteinases 1).

Physical form

Lyophilized from 20 mM TRIS, pH 9.0 + 0.1 mM Calcium Chloride + 100 mM Arginine.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
