Involved in regulating left/right asymmetric differentiation of the gustatory ASE neurons (PubMed:21555395). Plays a role in modulating expression of LIM/homeobox protein lim-6 (PubMed:21555395). Expressed very broadly throughout the embryo, from the one-cell stage until the comma stage, when expression diminishes, and is not observed after hatching in larvae or in adults (PubMed:21555395). Expressed in both ASE neurons in the comma-stage embryo (PubMed:21555395).
