Molecular mechanism of retroviral DNA integration

Kulkosky, Joseph, Skalka, Anna Marie·1994·Pharmacology & Therapeutics

Abstract

The integration of retroviral DNA appears to be obligatory for the efficient replication of retroviruses in their respective host cells. During a natural infection, integration takes place in a process that includes biochemically and temporally discrete steps. These are: (1) the removal of two nucleotides from the 3' ends of newly synthesized linear viral DNA in the host cell cytoplasm; (2) transport of the trimmed viral DNA to the nucleus within a viral protein/DNA complex; and (3) insertion of the viral DNA into host cell DNA via a concerted cleavage and ligation reaction. The cleavage of viral DNA and its subsequent joining to host DNA are catalyzed by the retroviral enzyme, integrase (IN). Elucidation of the mechanistic details of these catalytic activities of IN has relied heavily upon the use of relatively simple in vitro assays which recapitulate the in vivo reactions. These assays and the information derived from them should also facilitate the search for potential inhibitors of IN with the ultimate goal of providing a means to halt retroviral infections, such as that which causes the acquired immunodeficiency syndrome (AIDS), effectively.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The U5 and U3 regions contain attachment (att) sites required for integration of the reverse-transcribed RNA into the host genome.

    “These U5 and U3 regions also contain the attachment (att) sites required for the integration of the reverse-transcribed RNA into the host genome (see the U5 and U3 att sites in Fig. 3; Roth et al. 1989, Kulkosky and Skalka 1994, Coffin 1997, Masuda et al. 1998).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
