Disease
[GALC_MOUSE] Defects in Galc are the cause of the 'twitcher' phenotype; an autosomal recessive leukodystrophy similar to the human disease (Krabbe disease). This deficiency results in the insufficient catabolism of several galactolipids that are important in the production of normal myelin.
Function
[GALC_MOUSE] Hydrolyzes the galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride. Enzyme with very low activity responsible for the lysosomal catabolism of galactosylceramide, a major lipid in myelin, kidney and epithelial cells of small intestine and colon.[1]
