WormMine: ExpressionPattern Expr4266

• Pattern: Reporter genes that begin at -3190, -2021, -1248, and -517 bp upstream of the ATG of this alternate first exon 1 were expressed in body wall muscle cells, neurons in the head, nerve ring, ventral and dorsal nerve cords, neurons, and some epidermal cells in the tail. Weaker expression was also observed in pharyngeal muscles. The expression from promoter 2 started in the embryos at the 1.5-fold stage and was continuous throughout development. Expression from this internal promoter element is observed in vulval cells at the L4 stage and in adult hermaphrodites, including the uterine vulval cells uv1, 2, 3, and surrounding epithelium.
