Description of YBR101C: Hsp70 (Ssa1p) nucleotide exchange factor; cytosolic homolog of Sil1p, which is the nucleotide exchange factor for BiP (Kar2p) in the endoplasmic reticulum; protein abundance increases in response to DNA replication stress[1][2]

Alleles, Strains, and Phenotypes
Complete Deletion
Allele: deltafes1
Strain Background: W303 (see detailed notes from Rodney Rothstein and Stephan Bartsch for the W303 strain used in the study), RSY801
Phenotype(s): Temperature(Heat) Sensitive
The deletion of the FES1 gene leads to a strong thermosensitive phenotype as well as cycloheximide sensitivity [1] [3]
Interactions
Genetic
YBR101C is a suppressor of YDJ1
Strain Background: W303 (see detailed notes from Rodney Rothstein and Stephan Bartsch for the W303 strain used in the study)
Mutation type(s): deletion, point mutation (ydj1-151)
The thermosensitivity and cycloheximide sensitivity of the single deltafes1 and ydj1-151 mutants is partly suppressed in the double mutant. [1] [3]
Physical
Physical interaction with SSA1
Purified GST-Fes1p interacts with the ADP-bound form of (His6)-Ssa1p in GST pull down assays [1] [3]
Protein Details
Protein Function/Process
Fes1p is a nucleotide exchange factor that binds to the Hsp70 chaperone Ssa1p and inhibits its ATPase activity. Fes1p does not play an obvious role in protein folding, transport or degradation, but is involved in protein translation (presumably at the initiation step) [1] [3]
Protein Localization
Fes1p is a cytosolic protein (as shown by immunofluorescence and cell fractionation assays using a GFP-Fes1p construct) [1] [3]
Techniques and Reagents
Protein Purification
Fes1p was purified as a GST fusion protein from E. coli [1] [3]
