Abstract
The proteolytic activity of Membrane-type 1 Matrix Metalloproteinase (MT1-MMP) is crucial for cancer cell invasion and metastasis. To visualize the protease activity of MT1-MMP with high spatiotemporal resolution at the extracellular plasma membrane surface of live cancer cells, a genetically encoded fluorescent biosensor of MT1-MMP has been developed. Here we describe the design principles of the MT1-MMP biosensor, the characterization of the MT1-MMP biosensor in vitro, and the live-cell imaging protocol used to visualize MT1-MMP activity in mammalian cells. We also provide brief guidelines for observing MT1-MMP subcellular activity by fluorescence resonance energy transfer (FRET) in a cell migration assay.Entities:
