25844643 ellipsometric measurements of naRP2 demonstrated that its particular affinity for saturated phospholipids can be explained by its larger extent of insertion in this phospholipid monolayer compared to that in polyunsaturated phospholipid monolayers.
25292197 The ability of the restored RP2 protein level to reverse the observed cellular phenotypes in cells lacking RP2 indicates that translational read-through could be clinically beneficial for patients.
25078280 The methylation state of CpG sites close to the RP2 core promoter (GAAA)n repeat serves as a proxy measurement of X-chromosome inactivation in human and non-human primates.
24479636 A novel frameshift mutation in RP2 was detected. This mutation was located in exon 2 of the RP2 gene: a nucleotide C was inserted at 111 (c.111insC, Fig. 1A), which caused a protein translation frameshift
23372056 Direct sequencing of RPGR and RP2 allowed for identification of a disease-causing mutation in 21 families. Of these "adRP" families 19 had RPGR mutations, and two had RP2 mutations.
23150612 Based on our findings, we suggest that RPGR should be considered as a first tier gene for screening isolated males with retinal degeneration.
22183373 The localization of RP2 to basal bodies and cilia in photoreceptors and kidney cells has linked RP2 dysfunction with ciliopathies.
22072390 data support a role for RP2 in facilitating the membrane association and traffic of Gbeta1, potentially prior to the formation of the obligate Gbeta:Ggamma heterodimer; combined with other recent evidence, this suggests that RP2 may co-operate with Arl3 and its effectors in the cilia-associated traffic of G proteins
21285245 Data demonstrate that Importin beta2 is necessary for localization of retinitis pigmentosa 2 (RP2) to the primary cilium, and identify two distinct binding sites of RP2, which interact independently with Importin beta2.
20801516 Observational study of genetic testing. (HuGE Navigator)
20625056 An identifiable phenotype for RP2-X-linked retinitis pigmentosa aids in clinical diagnosis and targeted genetic screening.
20106869 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.
20021257 Our results expand the frequency and spectrum of mutations at RPGR and RP2 as well as their associated clinical phenotypes in Chinese patients.
19516003 A transversion (T>A) at position -9 in intron 3 of RP2 causes X-linked retinitis pigmentosa (XLRP) by altering the splicing pattern and highlights the pathogenicity of intronic variants.
18376416 RP2 is an efficient GAP for Arl3, with structural features similar to other GAPs
17724181 The proportion of RP2-mediated XLRP in the Danish population is higher and the proportion of RPGR-ORF15 is lower than reported in other studies.
17093403 Three ORF15 mutations and one RP2 mutation in five Japanese retinitis pigmentosa families.
16969763 Observational study of genotype prevalence. (HuGE Navigator)
16936086 In this cohort of XLRP families, as has happened in previous studies, RP3 also seems to be the most prevalent form of XLRP, and, based on the results, the authors propose a four-step protocol for molecular diagnosis of XLRP families.
16472755 The N-terminal 34 residues and beta helix domain of RP2 are required for interaction with Arl3.
16457815 The data suggest that RP2 may have previously unrecognized roles as a DNA damage response factor and 3' to 5' exonuclease.
14566651 Mutations in the RP2 gene is associated with X-linked retinitis pigmentosa
14564670 Observational study of genotype prevalence and gene-disease association. (HuGE Navigator)
14564670 Patients with RP2 mutations had, on average, lower visual acuity but similar visual field area, final dark-adapted threshold, and 30-Hz ERG amplitude compared with those with RPGR mutations
11992260 A comprehensive mutation analysis of RP2 and RPGR in a North American cohort of families with X-linked retinitis pigmentosa.
11847227 functional overlap with tubulin-specific chaperone cofactor C
11798852 The mutation 358C-->T is useful in analyzing the function of RP2 protein and gene diagnosis of X-linked retinitis pigmentosa (XLRP).
