Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  This construct was detected in the larva in the pharyngeal-intestinal valve, the rectum and some neurons of the tail. In the adult additional expression was seen in the excretory cells and in some unidentified cells in the middle of the body. Interestingly, the A4 promoter/gfp reporter was strongly up-regulated in the intestine of the newly formed dauer larva, while the intestine of the normal developmental stages lacks A4 expression.

A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine. pharyngeal-intestinal valve cardia WBbt:0005767
