MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of the P4 ATPase family of proteins, which are thought to be involved in a process called lipid flipping, whereby phospholipids are translocated inwards from the exoplasmic leaflet to the cytosolic leaflet of the cell membrane, which aids in generating and maintaining asymmetry in membrane lipids. This protein is predicted to contain an E1 E2 ATPase, a haloacid dehalogenase-like hydrolase (HAD) domain, and multiple transmembrane domains. Associations between this protein and cell cycle control protein 50A are important for translocation of phosphatidylserine across membranes. Mutations in this gene have been associated with cerebellar ataxia, mental retardation and disequilibrium syndrome (CAMRQ). In addition, a translocation breakpoint within this gene was observed in an individual with neurological dysfunction. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]
PHENOTYPE: Mice homozygotes for spontaneous mutations have abnormal gait and tremors, with axonal degeneration in central and peripheral neurons. Symptoms progress to immobility and death by 1-month of age. Heterozygotes show subtle locomotor abnormalities and are hyporesponsive to tail pinching. [provided by MGI curators]
