Function
The CHE-1 transcription factor plays a crucial role in defining the identity of ASE chemosensory neurons. It activates the expression of genes specifically required for ASE chemosensory neuron function, including seven-transmembrane receptors and guanylate cyclase. Moreover, CHE-1 is essential for regulating the left/right asymmetry observed in ASE chemosensory neurons by controlling the expression of genes like *cog-1* and *ceh-36*.
