Rha1, an Arabidopsis Rab5 Homolog, Plays a Critical Role in the Vacuolar Trafficking of Soluble Cargo Proteins
Open accessAbstract
Rab proteins are members of the Ras superfamily of small GTP binding proteins and play important roles in various intracellular trafficking steps. We investigated the role of Rha1, an Arabidopsis Rab5 homolog, in intracellular trafficking in Arabidopsis protoplasts. In the presence of a dominant-negative mutant of Rha1, soluble vacuolar cargo proteins such as sporamin:green fluorescent protein (Spo:GFP) and Arabidopsis aleurain like protein:GFP are not delivered to the central vacuole; instead, they accumulate as a diffuse or punctate staining pattern within the cell. Spo:GFP at the punctate stains observed in the presence of hemagglutinin:Rha1[S24N] is colocalized with endogenous vacuolar sorting receptor (VSR(At-1)), which is known to localize primarily to the prevacuolar compartment, whereas Spo:GFP in the diffuse pattern is associated with tonoplasts. Furthermore, expression of Rha1[S24N] causes the secretion of a portion of the vacuolar proteins into medium. However, the inhibitory effect of Rha1[S24N] on vacuolar trafficking is relieved partially by coexpressed wild-type Rha1. Based on these results, we propose that Rha1 plays a critical role in the trafficking of soluble cargoes from the prevacuolar compartment to the central vacuole.

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.
