A defective POT1-TPP1 complex leads to longer and fragile telomeres, which in turn promotes genomic instability and cancer.
several missense mutations in human cancers that disrupt the POT1C-TPP1 interaction, resulting in POT1 instability, were identified.
melanoma associated POT1 germline variants seem to be rare.
Results indicate that lenti-shRNA-mediated POT1-KD significantly reduced POT1 mRNA and protein expression. POT1-KD immediately downregulated c-Myc expression, which led to the inhibition of cell proliferation, tumorigenesis, and HDACi response
A role of POT1 germline mutations in cancer predisposition beyond melanoma development
study suggests that, gallstone does not affect telomere length and even after having increased telomere length, decreased expression of some shelterin genes in inflamed tissue might cause telomeres to cap improperly, possibly leading to telomere dysfunction and further, gallbladder carcinogenesis
loss-of-function mutations in protection of telomeres 1 (POT1) co-segregated with Chronic lymphocytic leukemia.
hPOT1 OB-folds are required to protect and prevent newly replicated telomeres from engaging in Alternative non-homologous end joining mediated fusions that would otherwise promote genome instability to fuel tumorigenesis.
the study identifies mutations in KRAS and POT1 as novel determinants of outcome after chemoimmunotherapy using chlorambucil and anti-CD20 treatment.
Lung fibroblasts deficient in Sirt1 or treated with a selective Sirt1 inhibitor exhibit increased cellular senescence and decreased TPP1 levels, whereas Sirt1 overexpression and pharmacological activation protect against CS-induced TPP1 reduction and telomeric DNA damage.
Binding of POT1-TPP1 unfolds telomere secondary structure to assist loading of additional heterodimers.
We found that NEK6-mediated phosphorylation of TPP1 Ser255 in G2/M phase regulates the association between telomerase activity and TPP1. Furthermore, we found evidence that POT1 negatively regulates TPP1 phosphorylation because the level of Ser255 phosphorylation was elevated when telomeres were elongated by a POT1 mutant lacking its OB-fold domains
Coats plus is caused by a defect in POT1/CST-dependent telomere fill-in
Downregulation of Protection of Telomeres 1 expression in myelodysplastic syndromes with 7q deletion.
The conservation between fission yeast Tpz1-Pot1 and human TPP1-POT1 interactions resulted in mapping a human melanoma-associated POT1 mutation (A532P) to the TPP1-POT1 interface.
Missense variant p.R117C is associated with cardiac angiosarcoma in TP-53 negative Li-Fraumeni-like families. Mutation carriers show reduced telomere-bound POT1 levels, abnormally long telomeres and increased telomere fragility.
OB-fold domain 1 of human POT1 recognizes both telomeric and non-telomeric DNA motifs
these data provide a molecular basis by which POT1-TPP1 increases the processivity of telomerase15. Further, we show that this increased processivity may arise from the dynamic sliding of POT1-TPP1 that induces fast translocation of telomerase.
The clinicopathological findings differed in the expression of hPOT1.
Expression of shelterin component POT1 is associated with decreased telomere length and immunity condition in humans with severe aplastic anemia.
The tissue expression analysis indicated that the swine POT1 gene is differentially expressed in tissues including muscle, heart, liver, fat, kidney, lung, pancreas and spleen.
This gene is a member of the telombin family and encodes a nuclear protein involved in telomere maintenance. Specifically, this protein functions as a member of a multi-protein complex that binds to the TTAGGG repeats of telomeres, regulating telomere length and protecting chromosome ends from illegitimate recombination, catastrophic chromosome instability, and abnormal chromosome segregation. Increased transcriptional expression of this gene is associated with stomach carcinogenesis and its progression. Alternatively spliced transcript variants have been described.
