N-Acetyl Alpha-D-Glucosaminidase (NAGLU)

Weber et al. (1996) reported the cloning of the NAGLU gene by enzyme protein purification, amino acid sequence determination, and database searches. A TFASTA search aligned the amino acid sequence to sequence in the 5-prime flanking region of the 17-beta-hydroxysteroid dehydrogenase-1 gene (HSD17B1), and this sequence was used to screen cDNA libraries.Northern blot analysis showed a single 2.7-kb mRNA transcript with high expression levels in liver, ovary, and peripheral blood leukocytes and measurable amounts of transcript in other tissues. The full-length cDNA sequence was cloned into an expression vector, and cultured CHO cells transfected with this vector showed a 17-fold increase in enzyme expression.
