SSA1 Proteins

靶点详情

  • 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.

    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

    25. The introduction of Ssa1p improves secretory proteins in Pichia pastoris secretion 4-7 times. PMID: 16889384

    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
