Genes associated with regulation of membrane-type matrix metalloproteinase-1 (MT1-MMP)-
mediated pro-MMP-2 processing were screened in 293T cells by a newly developed
expression cloning method. One of the gene products, which promoted processing of pro-
MMP-2 by MT1-MMP was claudin-5, a major component of endothelial tight junctions.
Expression of claudin-5 not only replaced TIMP-2 in pro-MMP-2 activation by MT1-MMP but
also promoted activation of pro-MMP-2 mediated by all MT-MMPs and MT1-MMP mutants …
