Predicted to enable heparan sulfate 6-O-sulfotransferase activity. Involved in heparan sulfate proteoglycan biosynthetic process, enzymatic modification and regulation of growth. Predicted to be located in membrane. Is expressed in neurons. Human ortholog(s) of this gene implicated in Paganini-Miozzo syndrome and hypogonadotropic hypogonadism 15 with or without anosmia. Orthologous to several human genes including HS6ST1 (heparan sulfate 6-O-sulfotransferase 1).
WB Description
hst-6 encodes the C. elegans ortholog of the heparan sulfate modifying enzyme heparan 6O-sulfotransferase; by homology, HST-6 is predicted to function in heparan sulfate biosynthesis by catalyzing the chain-modifying sulfation of the C6 hydroxyl group of the glucosamine subunits; during development, hst-6 activity is required for normal body size and nervous system development; an hst-6::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 neuronal tissues.
