靶點詳情

  • 功能：
    May play a role in the transport of polypeptides both across the mitochondrial membranes and into the endoplasmic reticulum. A functional difference between SSA1 and SSA2 proteins is expected. SSA1 can participate in the ATP-dependent disassembly of clathrin-coated vesicles.

    1. Hsp90 (Hsp82) and yeast Hsp70 (Ssa1), directly interact in vitro in the absence of the yeast Hop homolog (Sti1), and identify a region in the middle domain of yeast Hsp90 that is required for the interaction. PMID: 29463764
    2. Studied deletions of two major chaperone proteins, SSA1 and SSB1, from the HSP70 chaperone network in Sacchromyces cerevisiae. PMID: 25689132

    5. The major ubiquitin ligase targeting the superfluous Fas2 subunit to the proteasome is Ubr1. The ubiquitin-conjugating enzymes Ubc2 and Ubc4 assist the degradation process. PMID: 25564609
    6. Ssa1p and Swa2p cooperatively disassemble yeast clathrin coat baskets PMID: 23913685

    8. Data indicate that the Hsp70, Ssa1p, facilitates an interaction between a novel misfolded substrate and San1p. PMID: 23653356
    9. Sis1 and Hsp70 operate sequentially with the quality control E3 ubiquitin ligase Ubr1 to target short-lived green fluorescent protein for degradation. PMID: 23341891
    10. findings demonstrate that Hsp70 is a proximal sensor for Hsf1-mediated cytoprotection and can discriminate between two distinct environmental stressors PMID: 22809627
    11. T36 phosphorylation triggers displacement of Ydj1, allowing Ssa1 to bind the G1 cyclin Cln3 and promote its degradation; these results establish an active role for Hsp70 chaperones as signal transducers mediating growth control of G1 cyclin abundance and activity. PMID: 23217712
    12. the client binding domain of Hsc70 and Ssa1p binds two regions within alpha-Syn similar to a tweezer, with the first spanning residues 10-45 and the second spanning residues 97-102. PMID: 22843682

    24. A structural basis for the regulation of heat-shock proteins in S. cerevisiae is presented. PMID: 16737444
    25. The introduction of Ssa1p improves secretory proteins in Pichia pastoris secretion 4-7 times. PMID: 16889384
    26. Jjj1, when overexpressed, is able to partially substitute for the Zuo1:Ssb chaperone machinery by recruiting Ssa to the ribosome, facilitating its interaction with nascent polypeptide chains PMID: 17242366
    27. Stability experiments revealed that only Hsp70 proteins Ydj1-protected can hydrolyze ATP under prolonged stress. PMID: 17985367
    28. To determine how the mutations alter Hsp70 we analyzed biochemically the substrate-binding domain (SBD) mutant L483W and the nucleotide-binding domain (NBD) mutants A17V and R34K. PMID: 18706386
    29. Sse1 exploits a Bag-1-like mechanism to catalyze nucleotide release, which involves opening of the Ssa1 NBD by tilting lobe II. Hsp110 proteins use a unique binding mode to catalyze nucleotide release from Hsp70s by a functionally convergent mechanism PMID: 18948593
    30. These results suggest that cytosolic Hsp70 plays multiple roles in TBSV replication, such as affecting the subcellular localization and membrane insertion of the viral replication proteins as well as the assembly of the viral replicase. PMID: 19153242
    31. An in vitro replicase assembly assay with Ssa1p(ts) revealed that functional Ssa1p is required during the replicase assembly process, but not during minus- or plus-strand synthesis of Tombusvirus. PMID: 19748649
