For the sudden loss of central vision? The key to this question might be the composition of the lipofuscin. Based on the Stargardt disease phenotypes and the localization of ABCA4 in the photoreceptor outer segment, it was hypothesized that the lipofuscin that accumulates in Stargardt disease patients might be N-retinylidene-N-retinylethanolamine (A2E) [105, 106, 144], which is the Schiff base rea

Wing day using a standard calcium phosphate precipitation method or via FuGENE (Roche). Empty control plasmids were added to ensure that each transfection received the same amount of total DNA. To normalize the transfection efficiency, pRL-TK Renilla luciferase reporter plasmids were added to each transfection. The luciferase assays were performed using a Dual-Specific Luciferase Assay kit (Promeg
S. For instance, the eukaryotic mitogen-activated protein (MAP) cascade is an illustrious example of a tricyclic phosphorylation cascade (619). With respect to ammonium metabolism in E. coli, covalent modification is known to play a prime role in its regulation. Adenylylation of GS, uridylylation of GlnB and of GlnK, and phosphorylation of NRI and of NRII are the three relevant covalent modificati
In intensities from 20 time points, as obtained from the experiments described above, was analyzed as follows. The table containing protein names and respective intensities at all time points was loaded into R (version 3.0.0) (35) as a datamatrix (eset) object. Subsequently all rows containing proteins with their intensities over the 20 time points were filtered and processed in R using the follow
