The Saccharomyces cerevisiae peroxisomal import receptor Pex5p is monoubiquitinated in wild type cells.

The Journal of biological chemistry - 4 Mar 2005

Abstract excerpt

Pex5p is a mobile receptor for peroxisomal targeting signal type I-containing proteins that cycles between the cytoplasm and the peroxisome. Here we show that Pex5p is a stable protein that is monoubiquitinated in wild type cells. By making use of mutants defective in vacuolar or proteasomal degradation we demonstrate that monoubiquitinated Pex5p is not a breakdown intermediate of either system. Monoubiquitinated...
