The type 6 phosphodiesterase (PDE-6) from retinal rod photoreceptors is an alpha beta gamma 2 heterotetramer. The alpha- and beta-subunits contain catalytic sites for cGMP hydrolysis, whereas the gamma-subunits (P gamma) serve as a protein inhibitor of the enzyme. P gamma is believed to be expressed only in photoreceptors. Using RT-PCR, we have amplified the complete coding sequence for P gamma from mouse lung RNA. The expression of P gamma in this tissue may be related to its ability to interact the type 5 phosphodiesterase (PDE-5), which is the predominant cGMP binding protein in lung. We therefore suggest that P gamma may have a wider signaling role in mammalian cells than previously appreciated.
