We now report that homozygous or heterozygous [[CAPN1]]-null mutations in humans result in cerebellar ataxia and limb spasticity in four independent pedigrees. Calpain-1 knockout (KO) mice also exhibit a mild form of ataxia due to abnormal cerebellar development, including enhanced neuronal apoptosis, decreased number of cerebellar granule cells, and altered synaptic transmission. Enhanced apoptosis is due to absence of calpain-1-mediated cleavage of PH domain and leucine-rich repeat protein phosphatase 1 ([[PHLPP1]]), which results in inhibition of the Akt pro-survival pathway in developing granule cells. Injection of neonatal mice with the indirect Akt activator, bisperoxovanadium, or crossing calpain-1 KO mice with [[PHLPP1]] KO mice prevented increased postnatal cerebellar granule cell apoptosis and restored granule cell density and motor coordination in adult mice. Thus, mutations in [[CAPN1]] are an additional cause of ataxia in mammals, including humans.<br /> |mesh-terms=* Aging<br /> * Amino Acid Sequence<br /> * Animals<br /> * Animals, Newborn<br /> * Apoptosis<br /> * Calpain<br /> * Cell Count<br /> * Cerebellar Ataxia<br /> * Cerebellum<br /> * Enzyme Activation<br /> * Female<br /> * Humans<br /> * Intellectual Disability<br /> * Male<br /> * Mice, Knockout<br /> * Motor Activity<br /> * Muscle Spasticity<br /> * Mutation<br /> * Nuclear Proteins<br /> * Optic Atrophy<br /> * Phosphoprotein Phosphatases<br /> * Phosphorylation<br /> * Proto-Oncogene Proteins c-akt<br /> * Purkinje Cells<br /> * Spinocerebellar Ataxias<br /> * Synaptic Transmission<br /> |keywords=* apoptosis<br /> * ataxia<br /> * calpain-1<br /> * cerebellum<br /> * development<br /> |full-text-url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4927383<br /> }}</div>
