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]
A study in human heart tissue demonstrated that high-quality mRNA, including the GUSB used as an internal control, can be extracted from post-mortem samples, with its expression levels being independent of the post-mortem interval in non-degraded RNA samples [Partemi et al. DOI:10.1016/j.forsciint.2010.07.005]. Another study in human lung tissue from forensic autopsies validated the GUSB as one of the three most stable reference genes for mRNA normalization in quantitative PCR analyses across various causes of death [Du et al. DOI:10.1111/1556-4029.13199].
