WormMine: ExpressionPattern Expr11585

• Pattern: Head Paak-2::GFP expression is mostly seen in the excretory cell but is also observed in pharyngeal neurons, epithelial cells, a subset of ring neurons, amphid socket cells and head body wall muscles. Paak-2::GFP is also expressed in the posterior intestine, rectal gland and epithelial cells, and in phasmids. Paak-2::GFP is detected in vulval muscles. For a summary of Paak-2::GFP see table S10.

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

cell of epithelium, the layer of cells that cover the external surface of an organism as well as forming an inner lining between the tissues and organs of that organism and the external environment. In C. elegans epithelial cells include epithelium of the alimentary tract, intestinal cells, hypodermis, interfacial cells and somatic gonad cells.	epithelial cell	epithelium	WBbt:0003672
These cells include: B, F, Y, U, K' and K. All rectal epithelial cells contain secretory membrane stacks along this region facing the lumenal cuticle and produce some portion of the cuticular lining of the rectum. These are interfacial cells that connect the alimentary system to the main body syncytium.	rectal epithelial cell	rectal epithelium	WBbt:0008182
