WormMine: ExpressionPattern Expr3810

• Pattern: The pfn-2 promoter-GFP reporter assay confirmed its expression in the intestine.
• Primary Identifier: Expr3810
• Remark: The patterns of expression and localization of PFN-2 in the pfn-3 null mutants were indistinguishable from those in wild type.
• Subcellular Localization: In the pharynx, PFN-2 was diffusely localized to the cytoplasm of the pharyngeal cells but did not overlap with vinculin staining, which is generally known to concentrate beneath the plasma membrane.

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
the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.	pharynx	esophagus	WBbt:0003681
