WormMine: ExpressionPattern Expr686

• Pattern: Extensive expression observed in embryos. Larval stages and adults expression restricted to neural and muscle cells, virtually all neurons stain (head ganglia, ventral nerve cord and tail ganglia). Also hermaphrodite-specific neurons (HSNs) and canal-associated neurons (CANs) show expression. Most muscle cells show expression. Body wall muscle cells shows a punctate expression pattern of the translational gsa-1::gfp fusion, which may represent localization in dense bodies. Other muscle cells showing expression include those of the pharynx and uterine and vulva muscle cells. Transcriptional gsa-1::gfp fusion was expressed in the bilateral processes of the excretory cell and at low levels in the intestine.
• Primary Identifier: Expr686
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
• Subcellular Localization: Punctate expression pattern in body wall muscle cells, which may represent localization in dense bodies.

Definition	Name	Synonym	Primary Identifier
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772
