Rhodopsin Kinase Activity Modulates the Amplitude of the Visual Response in Drosophila

Balancing the Photoreceptor Proteome: Proteostasis Network Therapeutics for Inherited Retinal Disease
G C A T T A C G G C A T genes Review Balancing the Photoreceptor Proteome: Proteostasis Network Therapeutics for Inherited Retinal Disease Siebren Faber and Ronald Roepman * Department of Human Genetics and Radboud Institute for Molecular Life Sciences, Radboud University Medical Center, Geert Grooteplein Zuid 10, 6525 GA Nijmegen, The Netherlands * Correspondence: [email protected] Received: 10 June 2019; Accepted: 16 July 2019; Published: 24 July 2019 Abstract: The light sensing outer segments of photoreceptors (PRs) are renewed every ten days due to their high photoactivity, especially of the cones during daytime vision. This demands a tremendous amount of energy, as well as a high turnover of their main biosynthetic compounds, membranes, and proteins. Therefore, a refined proteostasis network (PN), regulating the protein balance, is crucial for PR viability. In many inherited retinal diseases (IRDs) this balance is disrupted leading to protein accumulation in the inner segment and eventually the death of PRs. Various studies have been focusing on therapeutically targeting the different branches of the PR PN to restore the protein balance and ultimately to treat inherited blindness. This review first describes the different branches of the PN in detail. Subsequently, insights are provided on how therapeutic compounds directed against the different PN branches might slow down or even arrest the appalling, progressive blinding conditions. These insights are supported by findings of PN modulators in other research disciplines. Keywords: protein trafficking; protein folding; protein degradation; chaperones; chaperonins; heat shock response; unfolded protein response; autophagy; therapy 1. Introduction The rod and cone photoreceptor (PR) cells are the most abundant cell types in the human retina, with ~6.4 million cones and up to 125 million rods per adult retina [1]. -

It would therefore be advantageous to separate out the different Extracts of lymphocytes from normal donors and from components of the leukocyte fraction before investigating patients with chronic lymphocytic leukemia (CLL) and acute their enzymatic activities. All previously reported work on the lymphoblastic leukemia were examined for a variety of enzymes of purine nucleotide metabolism was done at best in enzymes with activity for purine nucleotide biosynthesis, the whole white blood cell fraction. Those enzymes found to interconversion, and catabolism as well as for a selected be present included adenine and guanine phosphoribosyltrans number of enzymes involved in pyrimidine nucleotide ferase (2, 32), PNPase2 (7), deoxyadenosine deaminase (7), metabolism. Lymphocytes from all three donor types (normal, ATPase (4), and inosine kinase (21). CLL, acute lymphocytic leukemia) contained the following A detailed knowledge of the enzymatic pathways of purine enzymatic activities: adenine and guanine phosphoribosyl and pyrimidine nucleotide metabolism in normal lymphocytes transferase , adenosine kinase , nucieoside diphosphate kinase, and leukemia cells is important in elucidating any biochemical adenylate kinase, guanylate kinase, cytidylate kinase, uridylate differences that may exist.
