In addition to the reported expression pattern (Expr9873, Expr10754),
tmc-1 was expressed in body wall muscles, which is promoted by intronic DNA. The 3.6-kb promoter drives the expression in the reported ventral cord and head sensory neurons as-well-as SIBD, SIBV, ALA, AVH head neurons and I1, MC-pharyngeal neurons, and the PHC neurons in the tail.
