A protein which specifically binds to single stranded TTAGGGn repeats.
Nuclei from tissues of many vertebrates contain a soluble 37 kd protein which binds with a high degree of specificity to oligonucleotides which contain the G rich strand of the telomeric terminal repeats, TTAGGG. In some tissues this is an abundant nuclear protein.
متن کاملThe major herpes simplex virus DNA-binding protein holds single-stranded DNA in an extended configuration.
Properties of the major DNA-binding protein found in herpes simplex virus-infected cells were investigated by using a filter binding assay and electron microscopy. Filter binding indicated that the stoichiometry of binding of the protein with single-stranded DNA is approximately 40 nucleotides per protein molecule at saturation. Strong clustering of the protein in DNA-protein complexes, indicat...
متن کاملThe core of bluetongue virus binds double-stranded RNA.
Double-stranded RNA (dsRNA) viruses conceal their genome from the host to avoid triggering unfavorable cellular responses. The crystal structure of the core of one such virus, bluetongue virus, reveals an outer surface festooned with dsRNA. This may represent a deliberate strategy to sequester dsRNA released from damaged particles to prevent host cell shutoff.
متن کاملFluorescent single-stranded DNA-binding protein from Plasmodium falciparum as a biosensor for single-stranded DNA
Single-stranded DNA (ssDNA) is a product of many cellular processes that involve double-stranded DNA, for example during DNA replication and repair, and is formed transiently in many others. Measurement of ssDNA formation is fundamental for understanding many such processes. The availability of a fluorescent biosensor for the determination of single-stranded DNA provides an important route to a...
متن کاملRNA binding and R-loop formation by the herpes simplex virus type-1 single-stranded DNA-binding protein (ICP8).
In an effort to decipher the molecular mechanisms of homologous recombination during herpes simplex virus type-1 replication, we recently demonstrated that the virus-encoded single-stranded (ss) DNA-binding protein (ICP8) promotes the salt-dependent assimilation of ssDNA into a homologous plasmid, resulting in the formation of a displacement loop. In this paper, the results presented show for t...
