[Methylation of 3',5'-cGMP phosphodiesterase in retinal photoreceptor membranes]. 1987

N O Artem'ev, and R N Etingof

It was found that the level of methylation of phosphodiesterase (EC 3.1.4.17) and of proteins with Mr 61000 and 21000-26000 Da in isolated preparations of bovine retinal outer segments was sharply increased in the presence of cGMP, but not with cAMP. Preparations of the outer segment phosphodiesterase protein inhibitor, which inhibits the cyclic nucleotide hydrolysis, significantly decreased the methylation level. The degree of the enzyme methylation depended on the functional state of the outer segments: in light-induced preparations it was higher that in the dark ones.

UI	MeSH Term	Description	Entries
D008745	Methylation	Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed)	Methylations
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D010786	Photoreceptor Cells	Specialized cells that detect and transduce light. They are classified into two types based on their light reception structure, the ciliary photoreceptors and the rhabdomeric photoreceptors with MICROVILLI. Ciliary photoreceptor cells use OPSINS that activate a PHOSPHODIESTERASE phosphodiesterase cascade. Rhabdomeric photoreceptor cells use opsins that activate a PHOSPHOLIPASE C cascade.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
