ADP-ribosylation of neurofilaments by a cytoplasmic ADP-ribose transferase associated with free mRNP.
ADP-ribosylation of neurofilaments by an ADP-ribose transferase isolated from cytoplasmic ribonucleoprotein particles is demonstrated. The 150 kDa neurofilament subunit appears to be the main ADP-ribose acceptor with the transfer of ADP-ribose dimers or monomers. A binding of about 1 mole ADP-ribose per 8 moles of neurofilament subunits has been recorded. An interaction between neurofilaments' ADP-ribosylation and their phosphorylation state is demonstrated.
