GM1-gangliosidosis. Defective recognition site on beta-galactosidase precursor.

A T Hoogeveen, A J Reuser, M Kroos, H Galjaard.   

Abstract

Cultured fibroblasts from different variants of GM1-gangliosidosis synthesize normal amounts of 88-kDa beta-galactosidase precursor. Yet the amount of the mature 64-kDa form is reduced to 5-15% of normal values. In this communication it is shown that the mutation in the infantile and adult form of GM1-gangliosidosis interferes with the phosphorylation of precursor beta-galactosidase. As a result the precursor is secreted instead of being compartmentalized into the lysosomes and further processed. The impaired phosphorylation might be due to conformational changes of the precursor molecule.
