AtCHIP, a U-Box-Containing E3 Ubiquitin Ligase, Plays a Critical Role in Temperature Stress Tolerance in Arabidopsis
Open accessAbstract
The Arabidopsis gene AtCHIP encodes a protein with three tetratricopeptide repeats and a U-box domain, which is structurally similar to the animal CHIP proteins, a new class of E3 ubiquitin ligases. Like animal CHIP proteins, AtCHIP has E3 ubiquitin ligase activity in vitro. AtCHIP is a single-copy gene, and its transcript is up-regulated by several stress conditions such as low and high temperatures. However, increased AtCHIP expression alone was not correlated with increased stress tolerance; in fact, overexpression of AtCHIP in Arabidopsis rendered plants more sensitive to both low- and high-temperature treatments. Higher electrolyte leakage was observed in leaves of AtCHIP overexpression plants after chilling temperature treatment, suggesting that membrane function is likely impaired in these plants under such a condition. These results indicate that AtCHIP plays an important role in plant cellular metabolism under temperature stress conditions.

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.
