Binding of the delta subunit to rod phosphodiesterase catalytic subunits requires methylated, prenylated C-termini of the catalytic subunits

Results indicate that the type 6 phosphodiesterate delta subunit is strongly bound to the soluble phosphodiesterase catalytic subunits. Data reveal that the C-terminal methylation of the catalytic subunits may regulate the interaction of the delta subunit/phosphodiesterase catalytic subunits.
