Unlike other cytoskeletal motors that produce torque in a specific direction, cytoplasmic dynein generates torque in either direction, resulting in bidirectional helical motility along microtubules.
Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.

Uncovering the mechanisms by which the transcription factor NRSF contributes to the development of epilepsy reveals that the regulation of gene expression by transcription factors in the brain is more finely-tuned than previously thought.

Aneuploidy produces a protein expression signature characteristic of altered metabolism and redox homeostasis, and the loss of UBP6 ameliorates several aneuploidy-associated phenotypes.
Transcription elongation by the elongation factor P-TEFb promotes the epithelial–mesenchymal transition and metastasis of breast cancer cells, implicating inhibition of this factor as a potential treatment for the late stages of this cancer.

The accumulation of its product, cytidine triphosphate, encourages the enzyme CTP synthetase (CtpS) to form large-scale polymers and inhibits the enzyme's activity.
