WS295

Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  Expression was observed at all stages with a mosaic expression in the pharynx and in the nervous system: some head and tail neurons, some neurons of the dorsal and ventral nerve cords, and some commissures. At early larval stages, an intestinal expression was detected. Primary Identifier  Expr7862
Remark  Picture: Supplemental Figure 2. Subcellular Localization  In neurons, ppk-3::YFP fusion protein was localized as cytoplasmic dots in cell bodies and axons. In the intestine, PPK-3 displayed a diffuse localization with some punctate staining.

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
