MEC-2/Stomatin is required for aversive behaviour but dispensable for prey detection in the predatory nematode Pristionchus pacificus

Marianne Roca, James W. Lightfoot

The paper shows that MEC-2 is needed for aversive touch response but not for prey detection in P. pacificus, highlighting functional divergence in mechanosensory pathways.
