Abstract excerpt
The lysosomal disorder galactosialidosis is caused by deficiency of the protective protein in the absence of which the activities of the enzymes beta-galactosidase and neuraminidase are reduced. Aside from its protective function towards the two glycosidases, this protein has cathepsin A-like activity. A point mutation in the protective protein gene, resulting in the substitution of Phe412 with Val in the gene...
