Human cullin-RING ligases are buffered to a much greater extent than had been previously appreciated, and the roles of ubiquitin chain extension enzymes are far more nuanced at physiological concentrations.

Stem cells are found to continually rejuvenate the epidermis of the human parasite Schistosoma mansoni.

Multiple steps of the atypical cell cycles underlying Plasmodium gametogony are controlled by a divergent cyclin/cyclin-dependent complex.

Quantitative phosphoproteomics defines the substrates for Cyclin A/Cdk1 kinase during early mitosis and follow up studies validate that one identified substrate, MYPT1, influences the stability of k-MT attachments by regulating Plk1.

Genetic analysis reveals NADPH oxidase generated reactive oxygen species as signals to re-establish cellular homeostasis during aging via activating a transcriptional response.

The polarized orientation of the mitotic spindle in budding yeast arises from spindle pole structural and functional asymmetry subject to cell cycle control.

Lamellipodin, an important regulator of cytoskeletal and assembly cell migration, enhances the activity of Ena/VASP family actin polymerases by clustering them on leading-edge membranes and tethering them to actin filaments.

Aberrant neddylation of non-cullin substrates disrupts normal cell cycle progression.

High-throughput phenotypic screening followed by unbiased target identification reveals a new molecular glue HQ461 that induces CDK12-DDB1 interaction to promote degradation of Cyclin K via the ubiquitin proteasome system.

The Cajal body chaperone TCAB1 and scaffold protein Coilin are not required for telomerase activity in human cells.
