MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels of autophagy have been described in some malignant tumors, and a role for autophagy in controlling the unregulated cell growth linked to cancer has been proposed. This gene encodes a member of the autophagin protein family. The encoded protein is also designated as a member of the C-54 family of cysteine proteases. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a gene trap allele exhibit decreased autophagy, impaired swimming, circling, head tilting, and abnormal utricle, saccular, and otolith morphology. Mice homozygous for another gene trap allele exhibit partial preweaning lethality and impaired motor coordination and learning. [provided by MGI curators]
