It is an inhibitor of endopeptidases, can be modified by aliphatic amines, and combines with a number of hormones/cytokines such as beta-nerve growth factor (NGF) [Koo PH, Stach RW (1989): J Neurosci Res 22:247]. The objective of this study is to compare the NGF-binding properties of methylamine-modified human alpha 2M (MA-alpha 2M) versus normal alpha 2M and their effects on the biological activity of NGF and neurite extension by embryonic chicken dorsal root ganglia. As determined by gel filtration, polyacrylamide gel electrophoresis, and equilibrium binding studies, these two forms of alpha 2M are similar in their binding affinities, with MA-alpha 2M binding about twice as much NGF as normal alpha 2M. Both normal alpha 2M and MA-alpha 2M combine noncovalently with NGF, and prior modification of alpha 2M is unnecessary for the binding to occur. In contrast to normal alpha 2M, MA-alpha 2M potently inhibits the biological activity of NGF and exerts a dose-dependent inhibition on the NGF-stimulated neurite outgrowth by embryonic chicken dorsal root ganglia in culture. The inhibitory effect of MA-alpha 2M can be overcome by higher NGF concentrations, but is irreversible at lower NGF concentrations. Trypsin-modified alpha 2M combines covalently and noncovalently with more NGF than normal alpha 2M but has very little neurite inhibitory activity. The mechanism of inhibition by MA-alpha 2M is discussed."xsd:string |
