Tethering telomeric double- and single-stranded DNA-binding proteins inhibits telomere elongation.
Mammalian telomeres are composed of G-rich repetitive double-stranded (ds) DNA with a 3' single-stranded (ss) overhang and associated proteins that together maintain chromosome end stability. Complete replication of telomeric DNA requires de novo elongation of the ssDNA by the enzyme telomerase, with telomeric proteins playing a key role in regulating telomerase-mediated telomere replication. I...
متن کاملSingle-stranded DNA-binding Proteins
The emergence of DNA as the predominant hereditary material of life has necessitated the evolution of proteins whose sole function is the maintenance and care of these vital molecules. In a typical cell, there is a wide array of proteins with specialized functions in DNA metabolism that allow the cell to maintain and replicate its genome. In order to copy or make repairs to DNA, the double heli...
متن کاملS1 nuclease sensitivity of a double-stranded telomeric DNA sequence.
We examined structural properties of poly d(C4A2).d(T2G4), the telomeric DNA sequence of the ciliated protozoan Tetrahymena. Under conditions of high negative supercoiling, poly d(C4A2).d(T2G4) inserted in a circular plasmid vector was preferentially sensitive to digestion with S1 nuclease. Only the C4A2 strand was sensitive to first-strand S1 cutting, with a markedly skewed pattern of hypersen...
متن کاملDNA-induced dimerization of the single-stranded DNA binding telomeric protein Pot1 from Schizosaccharomyces pombe
Eukaryotic chromosome ends are protected from illicit DNA joining by protein-DNA complexes called telomeres. In most studied organisms, telomeric DNA is composed of multiple short G-rich repeats that end in a single-stranded tail that is protected by the protein POT1. Mammalian POT1 binds two telomeric repeats as a monomer in a sequence-specific manner, and discriminates against RNA of telomeri...
متن کاملSubstrate Recognition and Specificity of Double-Stranded RNA Binding Proteins
Recognition of double-stranded (ds) RNA is an important part of many cellular pathways, including RNA silencing, viral recognition, RNA editing, processing, and transport. dsRNA recognition is often achieved by dsRNA binding domains (dsRBDs). We use atomistic molecular dynamics simulations to examine the binding interface of the transactivation response RNA binding protein (TRBP) dsRBDs to dsRN...
