Intramolecular chaperones: polypeptide extensions that modulate protein folding

Shinde, Ujwal, Inouye, Masayori·2000·Seminars in Cell & Developmental Biology

Abstract

Several prokaryotic and eukaryotic proteins are synthesized as precursors in the form of pre-pro-proteins. While the pre-regions function as signal peptides that are involved in transport, the propeptides can often catalyze correct folding of their associated proteins. Such propeptides have been termed intramolecular chaperones. In cases where propeptides may not directly catalyze the folding reaction, it appears that they can facilitate processes such as structural organization and oligomerization, localization, sorting and modulation of enzymatic activity and stability of proteins. Based on the available literature it appears that propeptides may actually function as 'post-translational modulators' of protein structure and function. Propeptides can be classified into two broad categories: Class I propeptides that function as intramolecular chaperones and directly catalyze the folding reaction; and Class II propeptides that are not directly involved in folding.

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.
