Homologous recombination is a high-fidelity DNA repair pathway. Besides a critical role in accurate chromosome segregation during meiosis, recombination functions in DNA repair and in the recovery of stalled or broken replication forks to ensure genomic st ...

Telomerase is the ribonucleoprotein enzyme that elongates telomeres to counteract telomere shortening. The core enzyme consists of a reverse transcriptase protein subunit and an RNA subunit. The RNA subunit contains a short region that is used as a templat ...

Antisense oligonucleotides have been used to study the structure and function of small nuclear ribonucleoprotein (snRNP) complexes and were adapted and modified for the purification of a variety of RNPs. We describe methods for recombinant expression and r ...
Telomeres protect the eukaryotic chromosome ends from degradation and fusion. They are maintained by the ribonucleoprotein telomerase, the core of which is composed of a reverse transcriptase (TERT) and a RNA subunit. In the yeast Saccharomyces cerevisiae, ...
The tropism of retroviruses relies on their ability to exploit cellular factors for their replication as well as to avoid host-encoded inhibitory activities such as TRIM5α. N-tropic murine leukemia virus is sensitive to human TRIM5α (huTRIM5α) restriction, ...

Telomerase is a ribonucleoprotein enzyme that adds repetitive sequences to the ends of linear chromosomes, thereby counteracting nucleotide loss due to incomplete replication. A short region of the telomerase RNA subunit serves as template for nucleotide a ...
Telomerase uses an internal RNA moiety as template for the synthesis of telomere repeats. In Saccharomyces cerevisiae, the telomerase holoenzyme contains the telomerase reverse transcriptase subunit Est2p, the telomerase RNA moiety TLC1, the telomerase ass ...
Telomerase is the ribonucleoprotein enzyme responsible for the replication of chromosome ends in most eukaryotes. In the ciliate Euplotes aediculatus, the protein p43 biochemically co-purifies with active telomerase and appears to be stoichiometric with bo ...
Telomerase, the enzyme that extends chromosomal DNA ends in most eukaryotes, contains essential RNA and protein subunits. We have been studying telomere replication in hypotrichous ciliates such as Euplotes aediculatus, which have numerous short macronucle ...
By automated synthesis, we prepd. hybrid oligonucleotides consisting of covalently linked RNA and p-DNA sequences (p-DNA = 3'-deoxyribopyranose (4'->2')-oligonucleotides). The pairing properties of corresponding hybrid duplexes formed from fully complement ...
