Description
Bonemorphogeneticproteins(BMPs)constituteasubfamilywithintheTGF-βsuperfamilyofstructurallyrelatedsignalingproteins.Membersofthissuperfamilyarewidelydistributedthroughoutthebody,andareinvolvedindiversephysiologicalprocessesduringbothpre-andpostnatallife.LikeBMP-7,BMP-4 isinvolvedinthedevelopmentandmaintenanceofboneandcartilage.ReducedexpressionofBMP-4 isassociatedwithanumberofbonediseases,includingtheheritabledisorderFibrodysplasiaOssificansProgressiva.PeproTech’s E.coli-derivedBMP-4 isafullyactivehomodimericproteinconsistingoftwo106 aminoacidsubunits,whichcorrespondtoaminoacids303–408ofthefulllengthBMP-4 precursor.ThecalculatedmolecularweightofRecombinantHumanBMP-4(E.coli-derived)is23.9 kDa.ManufacturedusingallAnimal-Freereagents.
