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. However, the protein encoded by this gene is a member of the membrane-type MMP (MT-MMP) subfamily; each member of this subfamily contains a potential transmembrane domain suggesting that these proteins are expressed at the cell surface rather than secreted. This protein activates MMP2 by cleavage. The gene has previously been referred to as MMP25 but has been renamed MMP24. [provided by RefSeq, Jul 2008]
Function:
Activates progelatinase A. May also be a proteoglycanase involved in degradation of proteoglycans, such as dermatan sulfate and chondroitin sulfate proteoglycans. Cleaves partially fibronectin, but not collagen type I, nor laminin.
Subcellular Location:
Cell membrane; Single-pass type I membrane protein; Extracellular side.
Processed matrix metalloproteinase-24: Secreted, extracellular space, extracellular matrix. Note=Also shed from cell surface as soluble proteinase, by a proteolytic cleavage.
Tissue Specificity:
Expressed in brain. Expressed at low level in testis.
Post-translational modifications:
The precursor is cleaved by a furin endopeptidase.
Similarity:
Belongs to the peptidase M10A family.
Contains 4 hemopexin-like domains.
