Binding of a multivalent RNA-binding protein to mRNAs that are able to form pervasive RNA–RNA interactions induces formation of mesh-like condensates, whereas binding of mostly structured mRNAs induces sphere-like condensates.
Sonic Hedgehog is transported inside cytonemes with co-receptors that promote contact-mediated signal delivery to initiate rapid, receptor-dependent responses in recipient cells.
Bardet–Biedl syndrome 3 (BBS3) protein promotes phospholipase D to load onto the BBSome at the ciliary tip for moving out of the cilium via intraflagellar transport.

Leukocyte common antigen-related receptor protein tyrosine phosphatases (LAR-RPTPs) are precisely localized to synaptic appositions, but do not control the assembly and function of the presynaptic nerve terminal.
Spatial restriction of GPCR signaling at nascent synapses by adhesion complexes drives excitatory synapse formation and specificity in the hippocampus.

Reengineering the nucleotide-binding pocket of an extant ATPase to restore ancestral GTPase activity revealed an ATP-dependent intermediate required for function and suggested why the protein evolved to use ATP.

IL4i1 is an amino acid oxidase expressed in the mammalian immune system and snake venoms, which control diametrically opposite cell protection versus cell death pathways, respectively.
