Protein
F-box protein MET30
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Negatively regulates sulfur amino acids biosynthesis genes expression. Controls cell cycle function (being required for the G1/S transition and M-phase but not the S-phase), sulfur metabolism, and methionine biosynthesis as part of the E3 ubiquitin ligase complex SCF(Met30). Required for the efficient binding of CDC45 and MCM proteins to origins of replication. Involved in the S-adenosylmethionine (AdoMet)-mediated inhibition of the transcription function of MET4. In the context of the E3 ubiquitin ligase complex SCF(Met30), involved in the degradation of MET4 and the cellular response to cadmium. Required for efficient expression of G1 cyclins.
Similarity
Belongs to the WD repeat MET30/SCONB/SCON-2 family.
