WormMine: ExpressionPattern Expr3083

• Pattern: unc-89-A and -B are expressed in body-wall, pharyngeal and vulval muscles, unc-89-C is expressed in body-wall and vulval muscles (but not in the pharynx), and unc-89-D is expressed in only a few cells: vulval, intestinal, anal depressor and anal sphincter muscles. The identity of the anal depressor muscle was verified by examining expression of unc-89-D::GFP in adult males, which are known not to contain this muscle. Although all three promoters direct expression in vulval muscles, only the promoter for unc-89-D drives expression in the enteric muscles.
• Primary Identifier: Expr3083

type of cells that make up muscle layers in the pharynx.	pharyngeal muscle cell		WBbt:0005451
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
muscle associated with hermaphrodite vulva.	vulval muscle		WBbt:0005821
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
a saddle-shaped muscle cell that encircles the intestinal-rectal valve	anal sphincter muscle	lineage name: ABprpppppap	WBbt:0005798
intestinal muscle cell, attach to intestine and body wall anterior to anus	intestinal muscle	stomato-intestinal muscle	WBbt:0005796
