Using affinity-labelling methods, we demonstrate that PZP binds both TGF-beta 1 and TGF-beta 2 and that the binding characteristics are similar to those of the TGF-beta-alpha 2-macroglobulin interaction. Finally, we demonstrate that PZP inhibits the binding of TGF-beta 1 and TGF-beta 2 to their cell surface receptors." ; prov:wasQuotedFrompubmed:7513640 . sub:_8rdfs:label "Selventa" . sub:assertionprov:hadPrimarySourcepubmed:7513640 ; prov:wasDerivedFrombeldoc: , sub:_7 . }
