Abstract

Parkin, a product of the causative gene of autosomal‐recessive juvenile parkinsonism (AR‐JP), is a RING‐type E3 ubiquitin ligase and has an amino‐terminal ubiquitin‐like (Ubl) domain. Although a single mutation that causes an Arg to Pro substitution at position 42 of the Ubl domain (the Arg 42 mutation) has been identified in AR‐JP patients, the function of this domain is not clear. In this study, we determined the three‐dimensional structure of the Ubl domain of parkin by NMR, in particular by extensive use of backbone 15 N‐ 1 H residual dipolar‐coupling data. Inspection of chemical‐shift‐perturbation data showed that the parkin Ubl domain binds the Rpn10 subunit of 26S proteasomes via the region of parkin that includes position 42. Our findings suggest that the Arg 42 mutation induces a conformational change in the Rpn10‐binding site of Ubl, resulting in impaired proteasomal binding of parkin, which could be the cause of AR‐JP.

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.
