rcan-1 was expressed in various tissues including male tail and hypodermal seam cells, which also highly expressed
tax-6/calcineurin. RCAN-1::GFP is expressed in various head neurons, pharyngeal muscle, ventral nerve cord, and hypodermal seam cells where immunostaining for RCAN-1 was also prominent. GFP fluorescence was also detected in an excretory canal cell and vulva.
