Enables alpha-galactosidase activity and galactoside binding activity. Predicted to be involved in several processes, including glycosylceramide catabolic process; negative regulation of nitric oxide biosynthetic process; and negative regulation of nitric-oxide synthase activity. Located in lysosome. Used to study Fabry disease and lysosomal storage disease. Human ortholog(s) of this gene implicated in Fabry disease. Orthologous to human GLA (galactosidase alpha).
