Functional Descriptions hse-5

hse-5 encodes the C. elegans ortholog of the heparan sulfate modifying enzyme glucuronyl C5-epimerase; by homology, HSE-5 is predicted to function in heparan sulfate biosynthesis by catalyzing the chain-modifying epimerization of glucuronic acid to iduronic acid; during development, hse-5 activity is required for normal body size, locomotion, and nervous system development; an hse-5::gfp transcriptional reporter fusion is expressed beginning at early embryonic stages and continuing through adulthood; expression in embryos is nearly ubiquitous with later expression primarily restricted to the hypodermis and intestine.

intestine "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."

Phenotype Definition RNAi / Allele
axon fasciculation variant

"The ability of axons to converge and form a bundle of nerve fibres (fascicle) is compromised." [GO:0007413, WB:WBPerson2021, WB:WBPerson557]

Allele: WBVar00249516   WBPaper00006471   Observed
axon guidance variant

"Variations in the cue-directed extension of an axon towards a specific target site compared to control. (Axon guidance often depends on a combination of attractive and repulsive cues)." [GO:0048846, WB:WBPerson2021]
Allele: WBVar00094781   WBPaper00006471   Observed
axon midline crossing variant

"Regulated ventral midline crossing by axons vary either in the frequency of crossing events or the maintenance through development of process positions compared to control." [GO:0016199, WB:WBPaper00032007, WB:WBPerson712]

cord commissures fail to reach target

"Axon tracts fail to complete the connection between nerve cords. In C. elegans, these tracts grow circumferentially around the animal, completing the connection between the ventral and dorsal nerve cords." [WB:WBPaper00001499, WB:WBPaper00028984, WB:WBPerson712]
