What's a GeneRIF?

this study identifies ARL3 as a key player in prenylated protein trafficking in rod photoreceptor cells and establishes the potential role for ARL3 dysregulation in the pathogenesis of RP2-related forms of X-linked retinitis pigmentosa
Title: ARL3 regulates trafficking of prenylated phototransduction proteins to the rod outer segment.
RP2 has a role in cone photoreceptor sensory cilium elongation in mice
Title: Loss of retinitis pigmentosa 2 (RP2) protein affects cone photoreceptor sensory cilium elongation in mice.
we first performed detailed characterization of the Rp2-knockout (Rp2-KO) mice and observed early-onset cone dysfunction
Title: Long-term rescue of cone photoreceptor degeneration in retinitis pigmentosa 2 (RP2)-knockout mice by gene replacement therapy.
Our studies suggest that RP2 contributes to the maintenance of photoreceptor function and that cone opsin mislocalization represents an early step in XLRP caused by RP2 mutations.
Title: Ablation of the X-linked retinitis pigmentosa 2 (Rp2) gene in mice results in opsin mislocalization and photoreceptor degeneration.
We propose that RP2 regulation of Arl3 is important for maintaining Golgi cohesion, facilitating the transport and docking of vesicles and thereby carrying proteins to the base of the photoreceptor connecting cilium for transport to the outer segment.
Title: The retinitis pigmentosa protein RP2 links pericentriolar vesicle transport between the Golgi and the primary cilium.

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.

NR_110966.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (4) lacks an exon and contains multiple alternate 3' exons, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
