Cerebellar Hypoplasia in Mice Lacking Selenoprotein Biosynthesis in Neurons

Selenium exerts many, if not most, of its physiological functions as a selenocysteine moiety in proteins. Selenoproteins are involved in many biochemical processes including regulation of cellular redox state, calcium homeostasis, protein biosynthesis, and degradation. A neurodevelopmental syndrome called progressive cerebello-cortical atrophy (PCCA) is caused by mutations in the...
