CELLULAR FUNCTIONS, MECHANISM OF ACTION, AND REGULATION OF FTSH PROTEASE

Ito, Koreaki, Akiyama, Yoshinori·2005·Annual Review of Microbiology

Abstract

FtsH is a cytoplasmic membrane protein that has N-terminally located transmembrane segments and a main cytosolic region consisting of AAA-ATPase and Zn 2+-metalloprotease domains. It forms a homo-hexamer, which is further complexed with an oligomer of the membrane-bound modulating factor HflKC. FtsH degrades a set of short-lived proteins, enabling cellular regulation at the level of protein stability. FtsH also degrades some misassembled membrane proteins, contributing to their quality maintenance. It is an energy-utilizing and processive endopeptidase with a special ability to dislocate membrane protein substrates out of the membrane, for which its own membrane-embedded nature is essential. We discuss structure-function relationships of this intriguing enzyme, including the way it recognizes the soluble and membrane-integrated substrates differentially, on the basis of the solved structure of the ATPase domain as well as extensive biochemical and genetic information accumulated in the past decade on this enzyme.

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.
