Rabbit Anti-MMP9/FITC Conjugated antibody
background:
Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Most MMP's are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The enzyme encoded by this gene degrades type IV and V collagens. Studies in rhesus monkeys suggest that the enzyme is involved in IL-8-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling.

Function:
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 SLCterminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.
Subunit:
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.
Subcellular Location:
Secreted, extracellular space, extracellular matrix (Probable).
Tissue Specificity:
Produced by normal alveolar macrophages and granulocytes.
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.
DISEASE:
Intervertebral disc disease (IDD) [MIM:603932]: A common musculo-skeletal disorder caused by degeneration of intervertebral disks of the lumbar spine. It results in low-back pain and unilateral leg pain. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Metaphyseal anadysplasia 2 (MANDP2) [MIM:613073]: A bone development disorder characterized by skeletal anomalies that resolve spontaneously with age. Clinical characteristics are evident from the first months of life and include slight shortness of stature and a mild varus deformity of the legs. Patients attain a normal stature in adolescence and show improvement or complete resolution of varus deformity of the legs and rhizomelic micromelia. Note=The disease is caused by mutations affecting the gene represented in this entry.
Similarity:
Belongs to the peptidase M10A family.
Contains 3 fibronectin type-II domains.
Contains 4 hemopexin repeats.

MMP9亦称IV型胶原酶或明胶酶B，其主要功能为降解IV型胶原。因而它在肿瘤细胞突破基底膜屏障和浸润转移中起重要作用。
目前主要用于各种恶性肿瘤(如乳腺癌、胃肠道癌、卵巢癌、膀胱癌等)中的基底膜检测与转移浸润的研究。细胞外基质在维持正常组织结构与功能以及细胞生长和分化过程中起重要作用。细胞外基质动态平衡的失调与肿瘤细胞侵袭、转移和复发密切相关，基质金属蛋白酶(MMP9)是细胞外基质的降解酶，可降解Ⅳ、Ⅴ、Ⅸ、Ⅺ型胶原，在肿瘤的浸润、转移过程中起重要作用，近年为肿瘤研究的热点。
