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

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.

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

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

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

The survival of Drosophila amacrine neurons is controlled by neurotrophic signaling mediated by interactions between the cell surface protein DIP-γ and its partner Dpr11, which is expressed on presynaptic photoreceptors.

The dorsal raphe nucleus contains transcriptionally diverse cell classes that include subtypes of serotonergic neurons with distinct molecular and anatomical signatures.
