MMP14(redirected from MMP-X1)
MMP14A gene on chromosome 14q11-q12 that encodes matrix metalloproteinase 14, which specifically activates progelatinase A. It may be involved in actin cytoskeleton reorganisation by cleaving PTK7. Unlike other matrix metalloproteinases, which are secreted as inactive proproteins and activated when cleaved by extracellular proteinases, MMP14 is a transmembrane protein that is activated from its precursor by furin endopeptidase cleavage.
MMP14 may trigger invasion by tumour cells by activating progelatinase A on the surface of tumour cells.
