From: Genome-scale analyses of butanol tolerance in Saccharomyces cerevisiae reveal an essential role of protein degradation

Gene Function
PRE9 Alpha 3 subunit of the 20S proteasome. PRE9 encodes the only nonessential proteasome subunit.
UMP1 Chaperone required for correct maturation of the 20S proteasome.
YLR224W Subunit of the SCF ubiquitin ligase complexes, responsible of recognizing misfolded proteins.
UBP3 Ubiquitin-specific protease and its cofactor, respectively. Responsible of the deubiquitination of proteins. Important to maintain the pull of free ubiquitin in the cells.
BRE5
STP22 Components of the ESCRT-I, -II and –II complexes, respectively. Responsible of sorting ubiquitinated membrane proteins into Multivesicular Bodies (MVB) for their degradation in the vacuole.
SNF8
DID4
BRO1 Responsible of deubiquitination in the MBV. Important to maintain the pull of free ubiquitin.
VPS34 Vps34 and Vps15 form a complex responsible for the synthesis of phosphatidylinositol 3-phosphate, involved in endosomal membrane trafficking and in the regulation of protein sorting.
VPS15
PIH1 Component of the conserved R2TP complex. Interacts with Hsp90 to mediate assembly large protein complexes such as box C/D snoRNPs and RNA polymerase II.
SWI6 Transcription cofactor required for the unfolded protein response.
GET1 Subunits of the GET complex. Involved in the insertion of tail anchored proteins into the ER. Tail anchored proteins play a role in vesicular traffic and folding or degradation of membrane proteins.
GET2
VMA7 Subunit F of the eight-subunit V1 peripheral membrane domain of vacuolar H+−ATPase, and peripheral membrane protein that is required for vacuolar H+−ATPase function, respectively.
VMA22
SHE4 Protein that regulates myosin function; involved in endocytosis.
GND1 6-phosphogluconate dehydrogenase, required for adaptation to oxidative stress.
ANP1 Subunit of the alpha-1,6 mannosyltransferase complex. Involved in osmotic sensitivity.
GEP5 Protein of unknown function, required for mitochondrial genome maintenance.
THP2 Subunits of the THO complex. Involved in transcription elongation by RNA polymerase II and in telomere maintenance.
MFT1
SLA1 Cytoskeletal protein binding protein required for assembly of the cortical actin cytoskeleton.
SEC28 Epsilon-COP subunit of the coatomer; regulates retrograde Golgi-to-ER protein traffic.
MSE1 Mitochondrial glutamyl-tRNA synthetase.
NKP2 Non-essential kinetochore protein, subunit of the Ctf19 central kinetochore complex.
ALD6 Cytosolic aldehyde dehydrogenase, required for conversion of acetaldehyde to acetate.
SNT309 Member of the NineTeen Complex. Involved in splicing of nuclear RNAs via the spliceosome.
REG1 Regulatory subunit of Glc7p, involved in negative regulation of glucose-repressible genes.
HTL1 Component of the RSC chromatin remodeling complex. involved in telomere maintenance.
POL32 Third subunit of DNA polymerase delta, involved in chromosomal DNA replication.
DHH1 Cytoplasmic DExD/H-box helicase, stimulates mRNA decapping.
VRP1 Actin-associated protein involved in cytoskeletal organization and cytokinesis.
HOM2 Aspartic beta semi-aldehyde dehydrogenase, catalyzes the second step in the common pathway for methionine and threonine biosynthesis.
