DNA Transposition by the RAG1 and RAG2 Proteins

Open access
Hiom, Kevin, Melek, Meni, Gellert, Martin·1998·Cell

Abstract

The RAG1 and RAG2 proteins are known to initiate V(D)J recombination by making a double-strand break between the recombination signal sequence (RSS) and the neighboring coding DNA. We show that these proteins can also drive the coupled insertion of cleaved recombination signals into new DNA sites in a transpositional reaction. This RAG-mediated DNA transfer provides strong evidence for the evolution of the V(D)J recombination system from an ancient mobile DNA element and suggests that repeated transposition may have promoted the expansion of the antigen receptor loci. The inappropriate diversion of V(D)J rearrangement to a transpositional pathway may also help to explain certain types of DNA translocation associated with lymphatic tumors.

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.
