Description
TIMP-2 isanextracellularinhibitorofMMPs,includingMMP-1, –2, –3, –7, –8, –9, –10, –12, –13, –14, –15, –16and –19.ItbelongstotheI35(TIMP)familyofirreversIBLeproteaseinhibitorsthatfunctionaskeymodulatorsofextracellularmatrixdegradationduringtissuedevelopmentandremodeling.TIMP-2 canalsoactthroughanMMP-independentmechanisminhibitingendothelialcellproliferationinvitroanddemonstratesanti-angiogenicactivitiesinvivo.RecombinantHumanTIMP-2 isa21.8 kDaproteincontaining194 aminoacidresidues.
