Phosphodiesterase 6 gamma (Phosphodiesterase 6G cGMP Specific, PDE6 gamma, PDE6g, PDEG, Retinal Rod Photoreceptor cGMP Phosphodiesterase gamma)

The second messengers cAMP and cGMP are key regulatory molecules that are involved in a wide variety of signal transduction pathways, such as insulin secretion, platelet aggregation, smooth muscle relaxation, olfaction, and vision. Levels of cAMP and cGMP are regulated by their rate of synthesis by nucleotide cyclases and by their rate of hydrolysis by cyclic nucleotide phosphodiesterases (PDEs). PDEs form a superfamily of enzymes that catalyze the conversion of 3-prime, 5-prime-cyclic nucleotides to the corresponding nucleoside 5-prime-monophosphates. While mammalian PDEs are divided into major families based on their substrate specificities, kinetic properties, allosteric regulators, inhibitor sensitivities, and amino acid sequences, each family and even members within a family display distinct tissue, cell, and subcellular expression patters. This suggests that individual PDE family members are involved in discrete signal transduction pathways. PDE6 is the effector enzyme in the G protein-mediated signal transduction cascade in the visual system. There are five different subunits consisting of rod and cone specific catalytic subunits: alpha? (Cone), alpha (Rod), and beta (Rod), the inhibitory subunit gamma, and subunit delta of unknown function (which likely interacts with many other proteins besides the PDE6 family). The catalytic core of the PDE6 system is comprised of alpha?/alpha? homodimers in the cone and alpha/beta heterodimers in the rod. The C-terminus of both the catalytic and inhibitory subunits is modified by methylation, myristyolation and prenylation which have been shown to be critical for proper complex assembly and membrane association.\n\nApplications: \nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
