hst-1 encodes the C. elegans ortholog of N-deacetylase/N-sulfotransferase (NDST), a bifunctional enzyme that catalyzes N-deacetylation and N-sulfation of N-acetylglucosamine residues in heparan sulfate; loss of hst-1 activity has been reported to result in embryonic lethality at various stages of development, defects in ventral neuroblast migrations during epidermal enclosure, and cessation of egg production in injected hermaphrodites.
Predicted to enable [heparan sulfate]-glucosamine N-sulfotransferase activity and deacetylase activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process, polysaccharide chain biosynthetic process. Predicted to be located in Golgi apparatus. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 46. Is an ortholog of several human genes including NDST1 (N-deacetylase and N-sulfotransferase 1); NDST2 (N-deacetylase and N-sulfotransferase 2); and NDST3 (N-deacetylase and N-sulfotransferase 3).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
