May play an essential role in local proteolysis of the extracellular matrix and in leukocyte migration. Could play a role in bone osteoclastic resorption. Cleaves KiSS1 at a Gly-|-Leu bond. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.

Post-translational Modifications:

Processing of the precursor yields different active forms of 64, 67 and 82 kDa. Sequentially processing by MMP3 yields the 82 kDa matrix metalloproteinase-9.N- and O-glycosylated.

Subcellular Location:

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionGraphics by Christian Stolte

Subunit Structure:

Exists as monomer or homodimer; disulfide-linked. Exists also as heterodimer with a 25 kDa protein. Macrophages and transformed cell lines produce only the monomeric form. Interacts with ECM1.


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.Belongs to the peptidase M10A family.

Application: WB    Species:human;    Sample:A549 cells

Figure 3. A549/DDP and A549/PTX cells showed molecular and morphological changes that were consistent with EMT. (A) microscopy at x200 magnification was used to assess cell morphology. The A549 cells (parental cells) had an epithelioid, rounded cobblestone appearance and there was limited formation of pseudopodia. A549/PTX and A549/DDP cells exhibited a spindle-shaped morphology and an increased formation of pseudopodia, indicating a loss of cell polarity. (B) E-cadherin, β-catenin, vimentin, MMP-2 and MMP-9 which are EMT-related proteins, were assessed in terms of expression levels. EMT-related transcription factors (Snail, Slug, Twist and ZEB1) were measured in A549/PTX and A549/DDP cells using western blot analysis. (C) The expression changes were confirmed at the mRNA level by qRT-PCR. Expression was standardized to the expression of GAPDH and normalized to 1.0 in the parental cells (compared with the parental A549 cells, means ± SEM, n=3, * P<0.05)

Catalog Number :

(Blocking peptide available as AF5228-BP)

Price/Size :

Tips: For phospho antibody, we provide phospho peptide(0.5mg) and non-phospho peptide(0.5mg).

Function :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (immunoblot) and immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or immunostaining performed with the neutralized antibody.

Format and storage :

Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 10 mg/ml.The purity is >90%,tested by HPLC and MS.Storage Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.

Precautions :

This product is for research use only. Not for use in diagnostic or therapeutic procedures.
