WormMine: ExpressionPattern Expr1458

• Pattern: In transgenic animals carrying the fusion gene, an egl-19::GFP fluorescent signal was first detected in body wall muscles in 11/2-fold embryos, before the onset of embryonic muscle contraction. By the time of hatching, GFP fluorescence was found in pharyngeal muscles pm3, pm4, pm5 and pm7, in body wall muscles and in the anal depressor muscle. Expression was also found in the nervous system, including the pharyngeal neuron M4 and several neurons in the head, the ventral nerve cord and the preanal ganglion.
• Primary Identifier: Expr1458

Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.	body wall musculature	body muscle	WBbt:0005813
neuron with its cell body situated in the head, excluding the pharynx.	head neuron		WBbt:0006751
a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292
