The completion of neural tube closure requires small GTPase-regulated membrane protrusions from non-neural ectoderm cells at the tips of the neural folds.

The GLS2 enzyme suppresses cancer metastasis by interacting with the small GTPase Rac1 and inhibiting its activity.

Plexin controls the spatial distribution of synapses by locally inhibiting Rap2 small GTPase activity along the axon, and a Rap2 effector, TNIK, which also plays a key role in inhibiting synapse number.

High resolution structures of the essential human AAA+ ATPase TorsinA and its disease mutant in complex with an activator reveal details of the interaction that will guide drug design and further functional characterization.

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.

Conditional knockout of the small GTPase Cdc42 in excitatory neurons of the mouse forebrain leads to impaired long-term synaptic plasticity and impaired retrieval of remote memory.

BRG1 loss drives initiation and progression in human cancers through changes in specific differentiation programs in an AP-1-dependent manner.

BART is a co-GEF for ARL3 and maintains the active ARL3-GTP until it is recycled by ARL3 effectors.

Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.

A posttranslational regulatory mechanism for a Ras family small GTPase could open up new directions to understand and control the Ras family of proteins that are important for physiology and diseases.
