sub:_5 prov:value "from full text - PDGF exists as a dimer in various combinations, i.e. AA, BB, AB, CC and DD, binding two structurally related tyrosine kinase receptors, alpha and beta, with different affinities. The C- and D-chains are the recently isolated members that are proteolytically cleaved before binding the receptors. The alpha receptor binds A-, B- and C-chains, whereas the beta-receptor binds B- and D-chains" ;
