Hsp70 - Wikipedia
Hsp70 (encoded by three very closely related paralogs: HSPA1A, HSPA1B, and HSPA1L) is a stress-induced protein. High levels can be produced by cells in response to hyperthermia, oxidative stress, and changes in pH. Binding immunoglobulin protein (BiP or Grp78) is a protein localized to the endoplasmic reticulum. It is involved in protein ...

The Hsp70 chaperone network - Nature Reviews Molecular Cell …
2019年6月28日 · This knowledge showcases how the Hsp70 chaperone system controls diverse cellular functions, and offers new opportunities for the development of chemical compounds that modulate disease-related...
Hsp70 chaperones: Cellular functions and molecular ... - PMC
The mechanism by which Hsp70-chaperones assist the folding of non-native substrates is still unclear. Hsp70-dependent protein folding in vitro occurs typically on the time scale of minutes or longer. Substrates cycle between chaperone-bound and free states until the ensemble of molecules has reached the native state.
之一，热休克蛋白70 (heat shock protein 70, Hsp70) 是生物细胞中含量最高的一种热休克蛋白，可诱导性最强， 具有多种生物学功能，因此，又被称为主要热休克蛋白。
Hsp70 chaperone: a master player in protein homeostasis - PMC
Hsp70 plays a central role in disaggregation processes and, as discussed below, seemingly by different mechanisms throughout evolution. Hsp70 recruits and activates Hsp100 disaggregases 22 in bacteria, fungi, and plants to extract aggregated proteins 23.
Single-molecule evidence of Entropic Pulling by Hsp70 …
2024年10月8日 · We demonstrate that Hsp70s extract trapped polypeptide substrates from the nanopore by generating strong forces (equivalent to 46 pN over distances of 1 nm), that rely on the size of Hsp70.
Role of Hsp70 in Post-Translational Protein Targeting: Tail …
Overview of the Hsp70 functional cycle and its role in protein biogenesis. (A) The ATPase cycle of Hsp70 regulates the capture and release of substrate proteins and is driven by its cochaperones J-domain proteins (JDPs) and nucleotide exchange factors (NEFs), which catalyze the hydrolysis of ATP and the release of ADP, respectively.The various domains in Hsp70 are indicated.
Assays to measure small molecule Hsp70 agonist activity in vitro …
4 天之前 · Abstract: Hsp70 prevents protein aggregation and is cytoprotective, but sustained Hsp70 overexpression is problematic. Instead, we developed small molecule agonists that augment Hsp70 activity. Because cumbersome assays were required to assay agonists, we developed cell-based and in vivo assays in which disease-associated consequences of Hsp70 ...
Structure of Hsp90–Hsp70–Hop–GR reveals the Hsp90 client …
2021年12月22日 · Here we report the cryo-electron microscopy structure of the GR-loading complex, in which Hsp70 loads GR onto Hsp90, uncovering the molecular basis of direct coordination by Hsp90 and Hsp70.
