Co-immunoprecipitation and FRET reveal a direct association between Mmp14 and Itgb1. (A) Co-immunoprecipitation of endogenous Mmp14 and Itgb1. Protein complexes containing Mmp14 were immunoprecipitated from EpH4 cells cultured on a collagen 1-coated dish and probed for Mmp14 (top row) or Itgb1 (bottom row). (B) FRET analysis of monomeric Cypet-tagged MMP14F (FLAG tagged human MMP14) and monomeric Ypet-tagged ITGB1 exogenously expressed in EpH4 MECs. Ypet emission signal was detected as FRET signal when Cypet was excited. Scale bars: 10 μm.
