Smad and Schnurri transcription factors engage in context-dependent interactions as well as independent genomic activities, leading to regulation of collagen secretion to mediate body size regulation in C. elegans.

The opposing dopamine receptors Dop1R1 and Dop2R are both enriched around the pre- and postsynaptic sites of different types of neurons, including dopaminergic neurons, in the fly brain.

The mftG gene, present in the majority of mycofactocin gene clusters, encodes an oxidoreductase that facilitates ethanol utilization by reoxidation of mycofactocins and channeling electrons towards the respiratory chain.
