The N-end rule: functions, mysteries, uses

Open access
Varshavsky, A·1996·Proceedings of the National Academy of Sciences

Abstract

The N-end rule relates the in vivo half-life of a protein to the identity of its N-terminal residue. Similar but distinct versions of the N-end rule operate in all organisms examined, from mammals to fungi and bacteria. In eukaryotes, the N-end rule pathway is a part of the ubiquitin system. I discuss the mechanisms and functions of this pathway, and consider its applications.

  • The N-end rule and the SsrA tag are the best characterized mechanisms by which bacterial proteases recognize substrates.

    “Currently, the most well characterized mechanisms for substrate recognition by bacterial proteases are the N-end rule and the SsrA tag.”
  • The N-end rule ties a protein's half-life to its N-terminal amino acid.

    “The N-end rule relates the half-life of a protein to the N-terminal amino acid while the SsrA tag is an eleven amino acid tag that is added to the carboxy-terminus of incompletely translated proteins relegating them to degradation [54–55].”

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.
