additional information | sorting of Cps1p into the luminal vesicles of multivesicular bodies requires ubiquitination of their cytosolic domains by the ubiquitin ligases Rsp5p and/or Tul1p, whereas Sna3p, another integral membrane protein, does not require ubiquitination for entry into multivesicular bodies. Sna3p follows an ubiquitination-independent, but Rsp5p-mediated, sorting pathway to the vacuole | Saccharomyces cerevisiae |
Cloned (Comment) | Organism |
---|---|
GFP-Cps1p expressed in rsp5delta cells expressing wild-type or mutant HA-Rsp5p with WW domain mutations W257A, W359A, and W415A. GFP-Cps1p expressed in rsp5delta cells expressing HARsp5pWT, HA-rsp5pL733S or HA-rsp5G555D. GFP-Cps1p expressed in tul1delta cells, bsd2delta cells and sna3delta cells | Saccharomyces cerevisiae |

additional information | GFP-Cps1p accumulates in a prevacuolar compartment as well as on the limiting membrane of the vacuole in rps5WW1-3 cells with WW domain mutations. In rsp5L733S cells, GFP-Cps1p is detectable in the lumen of the vacuole, some is also found on the limiting membrane of the vacuole. In bsd2delta cells, GFP-Cps1p accumulates in the limiting membrane of the vacuole. In tul1delta cells sorting is also impaired. No defect in GFP-Cps1p vacuolar sorting in sna3delta cells | Saccharomyces cerevisiae |
