A reporter transgene driven by regions upstream of the
gcy-28.c isoform has widespread expression in neurons and other tissues (see Expr4542). Authors confirmed these results with additional reporters and found expression in almost all neurons, including AWC, as well as body wall muscle, gut, and hypodermis. The
gcy-28.a upstream region was expressed in many, but not all, neurons, and the
gcy-28.d upstream region was expressed in some neurons and in the gut.
