[https://www.uniprot.org/uniprot/PDE5A_BOVIN PDE5A_BOVIN] Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP (PubMed:8530505). Specifically regulates nitric-oxide-generated cGMP (By similarity).[UniProtKB:O76074]<ref>PMID:8530505</ref> [https://www.uniprot.org/uniprot/PDE6C_BOVIN PDE6C_BOVIN] As cone-specific cGMP phosphodiesterase, it plays an essential role in light detection and cone phototransduction by rapidly decreasing intracellular levels of cGMP.[UniProtKB:P51160]

The cGMP phosphodiesterase of rod photoreceptor cells, PDE6, is the key effector enzyme in phototransduction. Two large catalytic subunits, PDE6alpha and -beta, each contain one catalytic domain and two non-catalytic GAF domains, whereas two small inhibitory PDE6gamma subunits allow tight regulation by the G protein transducin. The structure of holo-PDE6 in complex with the ROS-1 antibody Fab fragment was determined by cryo-electron microscopy. The approximately 11 A map revealed previously unseen features of PDE6, and each domain was readily fit with high resolution structures. A structure of PDE6 in complex with prenyl-binding protein (PrBP/delta) indicated the location of the PDE6 C-terminal prenylations. Reconstructions of complexes with Fab fragments bound to N or C termini of PDE6gamma revealed that PDE6gamma stretches from the catalytic domain at one end of the holoenzyme to the GAF-A domain at the other. Removal of PDE6gamma caused dramatic structural rearrangements, which were reversed upon its restoration.
