Retbindin mediates light-damage in mouse retina while its absence leads to premature retinal aging.
Title: Retbindin mediates light-damage in mouse retina while its absence leads to premature retinal aging.
Absence of retbindin blocks glycolytic flux, disrupts metabolic homeostasis, and leads to photoreceptor degeneration.
Title: Absence of retbindin blocks glycolytic flux, disrupts metabolic homeostasis, and leads to photoreceptor degeneration.
Retbindin ablation causes a retinal phenotype characterized by time- and dose-dependent declines in rod and cone photoreceptor functions as early as 120 days of age. Whereas minor retinal ultrastructural defects were observed at all ages examined, a significant decline occurred in photoreceptor nuclei at 240 days of age ( approximately 36.8% rods and approximately 19.9% cones).
Title: Ablation of the riboflavin-binding protein retbindin reduces flavin levels and leads to progressive and dose-dependent degeneration of rods and cones.
Data suggest Retbindin as a possible flavin binding protein in the neural retina.
Title: The Potential Role of Flavins and Retbindin in Retinal Function and Homeostasis.
retbindin is an excellent candidate for binding retinal flavins and possibly participating in their transport from the extracellular space to the photoreceptors.
Title: Retbindin is an extracellular riboflavin-binding protein found at the photoreceptor/retinal pigment epithelium interface.

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.
