ARH3 is an enzyme that hydrolyses serine ADP-ribosylation, a recently uncovered post-translational protein modification.

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

The ciliary G-protein Arl13B – which is often mutated in Joubert syndrome – is the Guanine nucleotide exchange factor for the G-protein Arl3 and exclusively localizes to cilia.

Interactions between serines and molecules of ADP-ribose play an important role in signaling that the DNA in a cell has been damaged and needs to be repaired.

Serine residues in proteins are the primary targets for PARP-dependent ADP-ribosylation signalling upon DNA damage.

Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.

Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.

The RAB-28 GTPase regulates ciliary extracellular vesicle shedding, which may be important for neuron-glia communication.

Afferent-derived factors control the elaboration of appropriate and robust sizes of dendritic arbors by dynamically modulating dendritic growth parameters.
