WormMine: ExpressionPattern Expr12030

• Pattern: Both YFP::LNKN-1 and LNKN-1::YFP are similarly localized to the plasma membrane of many cells. LNKN-1 begins to be expressed in all somatic gonadal cells of the male, including the LC, the vas deferens precursor cells, and seminal vesicle precursor cells, starting in the early L3 stage and continuing through adulthood. It is also expressed in all somatic gonadal cells of the hermaphrodite, including the distal tip cells, anchor cell, uterine precursor cells, and spermatheca precursor cells. Other expression occurs in pharynx, pharyngeal-intestinal valve, intestine, excretory cell and canal, seam cells, a specialized subset of hypodermal cells, the vulval precursor cells of the hermaphrodite, and hook precursor cells in the male. YFP-tagged LNKN-1 is localized to the plasma membrane, exhibiting stronger localization to the sides of cell-cell contact in tissues such as the intestine, seam, and gonad.

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
A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine.	pharyngeal-intestinal valve	cardia	WBbt:0005767

Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom.	excretory canal	canal	WBbt:0005775

The components of the gonad that are separate from the germline proper. In hermaphrodite, these include five tissues which are all derived from the somatic primordium : the distal tip cells, the gonadal sheath, the spermatheca, the spermatheca-uterine valve (sp-ut) and the uterus.	somatic gonad	somatic germline	WBbt:0005785
