该基因编码一种降解糖胺聚糖的水解酶，包括硫酸乙酰肝素、硫酸皮肤素和硫酸软骨素。这种酶形成一个定位于溶酶体的四聚体该基因突变导致粘多糖病第七型。选择性剪接导致多个转录变体人类基因组中有许多这个位点的假基因。[由RefSeq提供，2014年5月]
This gene encodes a hydrolase that degrades glycosaminoglycans, including heparan sulfate, dermatan sulfate, and chondroitin-4,6-sulfate. The enzyme forms a homotetramer that is localized to the lysosome. Mutations in this gene result in mucopolysaccharidosis type VII. Alternative splicing results in multiple transcript variants. There are many pseudogenes of this locus in the human genome.[provided by RefSeq, May 2014]
