Histochemical evidence of cyclic nucleotide phosphodiesterase in photoreceptor outer segments.
نویسنده
چکیده
A histochemical demonstration of cyclic 3',5'-nucleotide phosphodiesterase in retinal photoreceptor outer segments is reported for the first time. The enzyme appears to be located on outer segment lamellae. It is not found in adjacent inner segment or nuclear regions. This histochemical localization is consistent with previously reported biochemical studies showing high phosphodiesterase activity in preparations of isolated rod outer segments.

Regulation of cyclic nucleotide concentrations in photoreceptors: an ATP-dependent stimulation of cyclic nucleotide phosphodiesterase by light.
Regulation of cyclic nucleotide concentrations in rod outer segments (Rana pipiens) has been further examined. The present studies show that illumination markedly diminishes the concentration of cyclic nucleotides in suspensions of photoreceptor membranes, but the locus of regulation is cyclic nucleotide phosphodiesterase (EC 3.1.4.c) (light-stimulated) and not adenylate cyclase. There is a mar...
متن کاملIdentification of 2':3'-cyclic nucleotide 3'-phosphodiesterase in the vertebrate retina.
The enzyme, 2':3'-cyclic nucleotide 3'-phosphodiesterase (2':3'-cNMP-3'-ase) has been used as a marker in the nervous system for the presence of myelin membrane or myelin-producing glial cells. In this study, goldfish and bovine neural retinas are found to have high levels of such a diesterase activity. Analysis of retinal tissue incubated with 2':3'-cAMP shows only 2'-AMP as the reaction produ...
متن کاملInvolvement of Cyclic GMP Phosphodiesterase Activator in an Hereditary Retinal Degeneration
CYCLIC NUCLEOTIDES mediate many aspects of normal cellular metabolism; thus, degradation as well as synthesis of these intracellular mediators must be strictly regulated. Phosphodiesterase (PDE), the enzyme of cyclic nucleotide catabolism, is present in mammalian tissues in multiple forms, which differ in substrate specificity, kinetic characteristics and sub-cellular localisation. Moreover, a ...
متن کاملLeber congenital amaurosis linked to AIPL1: a mouse model reveals destabilization of cGMP phosphodiesterase.
Leber congenital amaurosis (LCA4) has been linked to mutations in the photoreceptor-specific gene Aryl hydrocarbon interacting protein like 1 (Aipl1). To investigate the essential role of AIPL1 in retina, we generated a mouse model of LCA by inactivating the Aipl1 gene. In Aipl1(-/-) retinas, the outer nuclear layer develops normally, but rods and cones then quickly degenerate. Aipl1(-/-) mice ...
متن کاملCyclic-nucleotide Phosphodiesterase
Cyclic nucleotides have been implicated in the differentiation and function of the vertebrate retina. In the normal retina of DBA mice, the specific activity of cyclic-nucleotide phosphodiesterase (PDE), with cyclic-AMP as the substrate (cAMP-PDE), increases eightfold between the 6th and 20th postnatal day. Kinetic analysis of retinae from newborn mice reveals a PDE with a single Michaelis cons...
