Targeted Expression of Retinoschisin by Retinal Bipolar Cells in XLRS Promotes Resolution of Retinoschisis Cysts Sans RS1 From Photoreceptors.
Title: Targeted Expression of Retinoschisin by Retinal Bipolar Cells in XLRS Promotes Resolution of Retinoschisis Cysts Sans RS1 From Photoreceptors.
These and previous results led us to suggest an induced-fit binding mechanism for the interaction between retinoschisin and the Na/K-ATPase, which is dependent on threonine 240 in ATP1B2 allowing the accommodation of hyperflexible retinoschisin spikes by the associated protein-protein interaction patch on ATP1B2.
Title: Identification of the retinoschisin-binding site on the retinal Na/K-ATPase.
RS1 removal did neither influence glucose and glycogen accumulation 1 day after TBI nor up-regulation of inflammatory cytokines
Title: RS1 (Rsc1A1) deficiency limits cerebral SGLT1 expression and delays brain damage after experimental traumatic brain injury.
Results suggest a regulatory effect of retinoschisin on Na/K-ATPase signaling and localization, whereas Na/K-ATPase-dysregulation caused by retinoschisin deficiency could represent an initial step in XLRS pathogenesis.
Title: Retinoschisin is linked to retinal Na/K-ATPase signaling and localization.
retinoschisin is a novel regulator of MAP kinase signalling and exerts an anti-apoptotic effect on retinal cells.
Title: The X-linked juvenile retinoschisis protein retinoschisin is a novel regulator of mitogen-activated protein kinase signalling and apoptosis in the retina.
Based on this structure, we propose that RS1 couples neighboring membranes together through octamer-octamer contacts, perhaps modulated by interactions with other membrane components.
Title: Paired octamer rings of retinoschisin suggest a junctional model for cell-cell adhesion in the retina.
Changes in Rs1-knockout mice were associated with age related alterations in photoreceptor morphology and transcription factor expression that suggest delayed photoreceptor maturation.
Title: Photoreceptor pathology in the X-linked retinoschisis (XLRS) mouse results in delayed rod maturation and impaired light driven transducin translocation.
Time line analysis after short-term treatment with dorzolamide failed to show short-, intermediate-, or long-term evidence of structural improvement in Rs1h(-/y) mice.
Title: In vivo imaging reveals novel aspects of retinal disease progression in Rs1h(-/Y) mice but no therapeutic effect of carbonic anhydrase inhibition.
The results of this study demonstrated that loss of Rs1 gene function has a significant impact on the expression of photoreceptor transcription factor network genes, and morphological and functional defects in young (P21) Rs1-KO mice.
Title: Loss of retinoschisin (RS1) cell surface protein in maturing mouse rod photoreceptors elevates the luminance threshold for light-driven translocation of transducin but not arrestin.
RS1 is needed for preservation of synaptic structures but not synaptogenesis in retinoschisis model.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
