The
clp-7 reporter was active in neurons and co-localized with both the pan-neural
unc-119::gfp and the GABAergic
unc-47::gfp reporters. In addition, the
clp-7 reporter was expressed in cells of the ventral nerve cord. mRFP expressed from the
clp-7 gene promoter also co-localized with a
pes-6::gfp reporter, a marker for the excretory cell, which serves as the renal system of the worm. In addition, only the
clp-7p::nls::mrfp transcriptional reporter co-localized with the seam cell reporter scm::gfp.
clp-7 transcriptional reporters were also detected in other tissues, including the intestine, vulva, and hypodermis. The expression pattern remained unchanged over the course of larval development through to adulthood.
