An overhanging 3' terminus is a conserved feature of telomeres.

چکیده
The reactivity of single-stranded thymidines with osmium tetraoxide was used to demonstrate the existence of a terminal overhang of the G-rich strand of telomeres from two distantly related eucaryotes, the ciliated protozoan Tetrahymena spp. and the acellular slime mold Didymium spp. Conservation of a G-strand overhang at the molecular terminus of telomeres is consistent with our suggestion that an unusual DNA structure formed by the G-strand overhang is important for telomere function (E. Henderson, C. C. Hardin, S. K. Wolk, I. Tinoco Jr., and E. H. Blackburn, Cell 51:899-908, 1987).

Cloning yeast telomeres on linear plasmid vectors.
We have constructed a linear yeast plasmid by joining fragments from the termini of Tetrahymena ribosomal DNA to a yeast vector. Structural features of the terminus region of the Tetrahymena rDNA plasmid maintained in the yeast linear plasmid include a set of specifically placed single-strand interruptions within the cluster of hexanucleotide (C4A2) repeat units. An artificially constructed hai...
متن کاملRap1 affects the length and heterogeneity of human telomeres.
Telomere length is controlled in part by cis-acting negative regulators that limit telomere extension by telomerase. In budding yeast, the major telomere length regulator scRap1 binds to telomeric DNA and acts to inhibit telomere elongation in cis. Because the human Rap1 ortholog hRap1 does not bind to telomeric DNA directly but is recruited to telomeres by TRF2, we examined its role in telomer...
متن کاملDetection of Telomerase Components by Quantitative Real-time On-line PCR Analysis with the LightCycler
One of the important hallmarks of cancer is an aberrant growth control, resulting, for example, from genetic mutations in proto-oncogenes and tumor-suppressor genes, in cell-cycle control genes, or in specific genes that are linked to signal-transduction pathways, differentiation and apoptosis. Associated with aberrant growth control, most of the cancer cells have another important feature that...
متن کاملRecognition and processing of double-stranded DNA by ExoX, a distributive 3′–5′ exonuclease
Members of the DnaQ superfamily are major 3'-5' exonucleases that degrade either only single-stranded DNA (ssDNA) or both ssDNA and double-stranded DNA (dsDNA). However, the mechanism by which dsDNA is recognized and digested remains unclear. Exonuclease X (ExoX) is a distributive DnaQ exonuclease that cleaves both ssDNA and dsDNA substrates. Here, we report the crystal structures of Escherichi...
متن کاملHuman protection of telomeres 1 (POT1) is a negative regulator of telomerase activity in vitro.
The telomeric single-strand DNA binding protein protection of telomeres 1 (POT1) protects telomeres from rapid degradation in Schizosaccharomyces pombe and has been implicated in positive and negative telomere length regulation in humans. Human POT1 appears to interact with telomeres both through direct binding to the 3' overhanging G-strand DNA and through interaction with the TRF1 duplex telo...
