MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a DNA helicase which functions in the stability, protection and elongation of telomeres and interacts with proteins in the shelterin complex known to protect telomeres during DNA replication. Mutations in this gene have been associated with dyskeratosis congenita and Hoyerall-Hreidarsson syndrome. Read-through transcription of this gene into the neighboring downstream gene, which encodes tumor necrosis factor receptor superfamily, member 6b, generates a non-coding transcript. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2013] PHENOTYPE: Homozygous null mice display embryonic lethality with abnormal development of the neural tube, brain, heart, vasculature, placenta, and allantois and chromosomal abnormalities in differentiating cells.

Protein Function and Prediction |
The DNA helicase RTEL-1 is required to prevent excess crossovers during meiosis (1), genome stability (2), tumor avoidance (3), telomere maintenance (2;4;5), and DNA repair (6). Barber et al. determined that RTEL-1 negatively regulates recombination by disassembling D loop recombination intermediates during DNA repair (3). Vannier et al. have shown that RTEL-1 removes telomeric DNA secondary structures to function in the prevention of telomere fragility and loss (5). Without the expression of RTEL-1, T loops are inappropriately resolved, resulting in loss of the telomere as a circle (5). RTEL-1 also counteracts telomeric G-quadruplex DNA structures to ensure the stability of the telomere (4;5). Deletion of Rtel1 results in an increased number of sister chromatid exchange events, revealing that Rtel-1 functions in homologous recombination (2).

Expression/Localization |
Northern blot analysis detected Rtel in spleen, thymus, Peyer patch, kidney, and intestine, but not in brain, heart, lung, skeletal muscle, skin, and white fat tissue (7). Rtel is highly expressed in the testis, mainly in spermatogonia and meiotic spermatocytes (7). Rtel1 localizes transiently at telomeres (2).

Background |
Rtel1tm1.1Hdin/tm1.1Hdin; MGI:3772371
involves: 129S1/Sv * 129X1/SvJ * C57BL/6 * FVB/N * SJL
Homozygous null mice display embryonic lethality (by E11.5) with abnormal development of the neural tube, brain, heart, vasculature, placenta, and allantois and chromosomal abnormalities in differentiating cells (8).
Rtel1tm1Pml/tm1Pml; MGI:3052235
involves: 129S1/Sv * 129X1/SvJ
Homozygous null mice also display embryonic lethality (by E11.5) with abnormal development of the neural tube, floor plate, brain, neural crest, placenta, muscle, and heart as well as abnormal cell differentiation with shorter telomere length and chromosomal abnormalities in differentiating cells (7). Homozygote embryos are decreased in size by E8.5 (7).
