The Rag-family GTPases, known activators of TOR complex 1 (TORC1), also function as attenuator that prevents deregulated hyperactivation of TORC1 signaling.

A critical second step in DNA tethering by cohesin occurs after its stable binding to DNA, and this second step is modulated by the Smc3 ATPase active site in Saccharomyces cerevisiae.

A small GTPase within the flagellum can participate in the control of transport from the base to the tip of the flagellum, and back again.

Structural and biochemical studies indicate that AAA+ ATPase employ a general mechanism to translocate a variety of substrates, including extended polypeptides, hairpins, crosslinked chains, and chains conjugated to other molecules.

An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.

DNA synthesis by DNA polymerase V is regulated by an intrinsic DNA-dependent ATPase activity which has not been observed for any other polymerase.

The human Origin Replication Complex is shaped as a shallow corkscrew in a classic AAA+ organization reminiscent of clamp loader complexes with highly controlled ATPase activity as exemplified by Meier-Gorlin syndrome mutations.

The H+ influx coupled to nutrient uptake and the plasma membrane H+-ATPase are central actors of the activation of target of rapamycin complex 1 (TORC1) in budding yeast Saccharomyces cerevisiae..

Genetic labeling of cells that survive executioner caspase activity in Drosophila reveals distinct patterns in different tissues.

The cryo-electron microscopy structure of an assembly of the WAVE Regulatory Complex and its activator, the Rac GTPase, plus complementary biochemistry and biophysics, reveal a novel activation mechanism involving two distinct Rac binding sites.
