Cdc48 cofactor Shp1 regulates signal-induced SCF(Met30) disassembly.
Title: Cdc48 cofactor Shp1 regulates signal-induced SCF(Met30) disassembly.
Study revealed that two essential Skp, Cullin, F-box (SCF) ubiquitin ligases defined by the F-box proteins Met30 and Cdc4 cooperatively regulate Cse4 (S. cerevisiae homolog of human centromere protein-A (CENP-A)) proteolysis under normal physiological conditions. Results suggest SCF-Met30/Cdc4-mediated proteolysis of Cse4 is one of the major mechanisms that prevents stable maintenance of Cse4 at non-centromeric regions.
Title: Skp, Cullin, F-box (SCF)-Met30 and SCF-Cdc4-Mediated Proteolysis of CENP-A Prevents Mislocalization of CENP-A for Chromosomal Stability in Budding Yeast.
This ubiquitylation and degradation pathway acts on Met30 that is dissociated from Skp1. Unexpectedly, this pathway required the cullin component Cdc53/Cul1 but was independent of the other central SCF component Skp1
Title: Skp1 Independent Function of Cdc53/Cul1 in F-box Protein Homeostasis.
In Saccharomyces cerevisiae, transcription of the MET regulon is controlled by ubiquitination of the transcription factor Met4, which is carried out by the SCF(Met30) E3 ubiquitin ligase.
Title: Multiple inputs control sulfur-containing amino acid synthesis in Saccharomyces cerevisiae.
The stability of these DNA-binding cofactors is regulated by SCF(Met30).
Title: A transcriptional activator is part of an SCF ubiquitin ligase to control degradation of its cofactors.
Met32 has a regulatory role as part of the Cbf1-Met4 complex as shown by the met30 cell cycle defect
Title: A dominant suppressor mutation of the met30 cell cycle defect suggests regulation of the Saccharomyces cerevisiae Met4-Cbf1 transcription complex by Met32.
the recruitment of Met4p to the SCF(Met30p) complex itself results in inactivation of Met4p, independently of its ubiquitination
Title: Identification of residues in the WD-40 repeat motif of the F-box protein Met30p required for interaction with its substrate Met4p.
The association of Met30 with Skp1 but not with its substrate Met4 was inhibited in cells treated with cadmium
Title: The yeast ubiquitin ligase SCFMet30 regulates heavy metal response.
data suggest that Met30 regulates several aspects of the cell cycle, including G(1)-specific transcription, initiation of DNA replication, and progression through M phase
Title: The F-box protein Met30 is required for multiple steps in the budding yeast cell cycle.
