WormMine: ExpressionPattern Expr10766

• Pattern: SHN-1::GFP expressed from embryo to adult. SHN- 1::GFP is expressed in neurons including nerve cords, pharynx, pharyngeal-intestinal valve, intestine, vulva, rectal epithelial cells, tail ganglia and male tail. SHN-1 protein is expressed from the embryonic stage to adulthood and tissue localization overlapped with SHN-1::GFP expression patterns in the pharynx, pharyngeal-intestinal valve, intestine, nerve cords, and tail region in addition to sperm.
• Primary Identifier: Expr10766
• Subcellular Localization: Immunogold electron microscopy in wild-type hermaphrodites and males showed signals in the vesicle-like structures of intestinal and pharyngeal cells, and in the tail region, and most clearly seen in the male germline in developing sperm and in the presumptive pseudopodia, structures for motility of mature sperm.

female genital.	vulva		WBbt:0006748
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
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 large process bundle that runs along the vental mid-line extending from the ventral region of the nerve ring.	ventral nerve cord	ventral cord	WBbt:0005829
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
Major cell type of nervous tissue, specialized for transmission of information in the form of patterns of impulses.	neuron	neurone	WBbt:0003679
a bundle of nerve processes that runs along the dorsal mid-line of the animal.	dorsal nerve cord	dorsal cord	WBbt:0006750
Male haploid germ cell.	sperm	spermatozoa	WBbt:0006798
Gonochoristic organism that can produce male gametes.	male	male organism	WBbt:0007850
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
ganglion in the tail region (posterior to rectum).	tail ganglion		WBbt:0006977
