Glutamate is a key regulator of omega turns.

N2, glr-1(LF), glr-1 KD, npr-9(LF), npr-9(LF);glr-1 KD, and npr-9(GF) were tested for the frequency of reversals that terminate with an omega turn during off food conditions Data are presented as mean +/- standard error (SE) with at least 5 animals assayed in three independent experiments analyzed via an unpaired two-tailed t test with Welsch’s correction. *** p < .001, significantly different from wild-type animals under identical conditions.
