Characterization of HSP90 isoforms in transformed bovine leukocytes infected with Theileria annulata [PDF]
HSP90 chaperones are essential regulators of cellular function, as they ensure the appropriate conformation of multiple key client proteins. Four HSP90 isoforms were identified in the protozoan parasite Theileria annulata.

Transcriptional regulation of human NMNAT2: insights from 3D genome sequencing and bioinformatics
NMNAT2 is a valuable drug target, as low levels increase the risk of neurodegeneration. We employed 4C‐seq to identify NMNAT2 regulatory regions in the human genome, revealing distinct interactomes of the NMNAT2 promoter in undifferentiated and neuron‐like SH‐SY5Y cells. Additionally, we uncovered NMNAT2‐associated genes and transcription factors. This

Deletion of heat shock protein 60 in adult mouse cardiomyocytes perturbs mitochondrial protein homeostasis and causes heart failure. [PDF]
To maintain healthy mitochondrial enzyme content and function, mitochondria possess a complex protein quality control system, which is composed of different endogenous sets of chaperones and proteases.

The ribosome‐associated complex regulates cytosolic translation upon mitoprotein‐induced stress
Defects in mitochondrial protein import trigger a stress response. The contribution of translation regulation to such a response is only partially understood. We demonstrate that the deletion of mitochondrial surface proteins (TOM70/TOM71) leads to defects in mitochondrial biogenesis and slow growth.

Mechanisms of Resistance to Hsp90 Inhibitor Drugs: A Complex Mosaic Emerges
The molecular chaperone Hsp90 holds great promise as a cancer drug target, despite some of the initial clinical trials of Hsp90 inhibitor drugs having not lived up to expectation.

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle
DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.
