WormMine: ExpressionPattern Expr1805

• Pattern: AX4: Although pAX4 contained the full-length aex-1 genomic sequence and was capable of rescuing all aex-1 phenotypes, the fluorescence of this fusion protein was extremely weak. pAX3: Expression of this fusion protein was observed in intestine, some amphid neurons, and body-wall muscles. Anterior and posterior, but not central, intestinal cells had detectable GFP fluorescence. Four neurons in the amphid had observable GFP fluorescence; this was observed only at a late adult stage when using pAX3 but not when using pAX4. The exact identities of these neurons are uncertain, but based on their positions, they do not appear to be the GABAergic AVL and DVB neurons required for the defecation behavior.

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
