BAIT

UBP3

BLM3, mRNA-binding ubiquitin-specific protease UBP3, L000002417, S000086717, YER151C
Ubiquitin-specific protease involved in transport and osmotic response; interacts with Bre5p to co-regulate anterograde and retrograde transport between the ER and Golgi; involved in transcription elongation in response to osmostress through phosphorylation at Ser695 by Hog1p; inhibitor of gene silencing; cleaves ubiquitin fusions but not polyubiquitin; also has mRNA binding activity; protein abundance increases in response to DNA replication stress; role in ribophagy

PBP1

MRS16, L000003967, YGR178C
Component of glucose deprivation induced stress granules; involved in P-body-dependent granule assembly; similar to human ataxin-2; interacts with Pab1p to regulate mRNA polyadenylation; interacts with Mkt1p to regulate HO translation; protein increases in abundance and relative distribution to the nucleus increases upon DNA replication stress

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Cdc48 and Ufd3, new partners of the ubiquitin protease Ubp3, are required for ribophagy.

Ubiquitin-dependent processes can be antagonized by substrate-specific deubiquitination enzymes involved in many cellular functions. In this study, we show that the yeast Ubp3-Bre5 deubiquitination complex interacts with both the chaperone-like Cdc48, a major actor of the ubiquitin and proteasome system, and Ufd3, a ubiquitin-binding cofactor of Cdc48. We observed that these partners are required for the Ubp3-Bre5-dependent and starvation-induced selective ... [more]
