Adaptor protein that links actin to clathrin and endocytosis; involved in membrane cytoskeleton assembly and cell polarization; present in the actin cortical patch of the emerging bud tip; dimer in vivo; Required for cellular morphogenesis and polarization of the cortical cytoskeleton. It might act in concert with proteins such as CDC42 and CDC43 to limit the region of cortical patch formation to the cortex of the bud. Required for the accumulation and/or maintenance of plasma membrane H(+)-ATPase on the cell surface (968 aa)

Ubiquitin carboxyl-terminal hydrolase, ubiquitin-specific protease that cleaves ubiquitin-protein fusions (754 aa)

Ubiquitin-specific protease that specifically disassembles unanchored ubiquitin chains; involved in fructose-1,6-bisphosphatase (Fbp1p) degradation; similar to human isopeptidase T; Has a role in the negative regulation of gluconeogenesis. Required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBPase). Accelerates proteasomal breakdown of ubiquitinated proteins as it disassembles free ubiquitin chains that would compete with ubiquitinated proteins to bind to the proteasome (781 aa)

Ubiquitin-specific protease; cleaves ubiquitin from ubiquitinated proteins; present in the nucleus and cytoplasm; Ubiquitin carboxyl-terminal hydrolase that recognizes ubiquitin chains that stabilize FZO1 and promote mitochondrial fusion. UBP12 deubiquitylates FZO1 only after oligomerization (1254 aa)

Cochaperone protein; regulates activity of adenylyl cyclase Cyr1p; involved in kinetochore complex assembly; associates with the SCF (Skp1p/Cdc53p/F box protein) ubiquitin ligase complex; acts as a linker between Skp1p and HSP90 complexes; Involved in ubiquitination and subsequent proteasomal degradation of target proteins. Required for both entry into S phase and kinetochore function. Also involved in cyclic AMP (cAMP) pathway, possibly by participating in the assembly or the conformational activation of specific multiprotein complexes (395 aa)

Ubiquitin-specific protease situated in the base subcomplex of the 26S proteasome, releases free ubiquitin from branched polyubiquitin chains; works in opposition to Hul5p polyubiquitin elongation activity; mutant has aneuploidy tolerance; Predominant proteasome-associated deubiquitinase which releases ubiquitin from the proteasome targeted ubiquitinated proteins. Ensures the regeneration of ubiquitin at the proteasome. Has proteasome-inhibitory activity and delays the degradation of ubiquitinated proteins to provide a time window allowing gradual deubiquitination of the substrate. Sta [...] (499 aa)

Deubiquitinating enzyme anchored to the outer mitochondrial membrane, probably not important for general mitochondrial functioning, but may perform a more specialized function at mitochondria (499 aa)

Sterol regulatory element binding protein, induces transcription of sterol biosynthetic genes and of DAN/TIR gene products; Ecm22p homolog; relocates from intracellular membranes to perinuclear foci on sterol depletion; Transcription factor that is involved in activation of anaerobic genes such as DAN/TIR cell wall mannoprotein genes and YML083c. Appears to bind to anaerobic response elements (AR1) with the consensus sequence 5’-TCGTTYAG-3’ present in the promoter regions of DAN/TIR genes. Involved in sterol uptake and regulation of the sterol biosynthesis. Binds to sterol regulatory e [...] (913 aa)
