Expression post hatching only in subset of ventral nerve cord (possibly VB nerves). String of ten nerve bodies linked by processes (5 either side of vulva) with process to nerve ring and back to two more ventral cells. Also process in tail divides with one ventral branch and one branch to dorsal side. Occasional expression in vulval muscles.
The C+C enhancer (pOK17.21) activates frequent expression in all pharyngeal muscles. the C+C enhancer also activates expression in non-muscle cells in the pharynx. Expression induced by the C+C enhancer was observed in all pharyngeal cell types including gland cells, neurons and marginal cells as well as muscles. These results define C as an organ-specific subelement.
