MGI Phenotype FUNCTION: This gene encodes a lysosomal serine protease that cleaves N-terminal tripeptides from protein substrates. The encoded preproprotein undergoes autocatalytic processing to generate a mature enzyme. Mice lacking the encoded protein exhibit a progressive neurodegeneration and a greatly shortened lifespan. At the cellular level, mice lacking the encoded protein exhibit accumulation of autofluorescent lipopigments. Mutations in the human ortholog of this gene cause classical late-infantile neuronal ceroid lipofuscinosis. [provided by RefSeq, Nov 2015]
PHENOTYPE: Mice homozygous for targeted mutations exhibit progressive motor defects, reduced lifespan, and respiratory difficulty. One mutation also shows extensive neuronal degeneration and an accumulation of lysosomal storage material. Mice homozygous for a different allele exhibit prenatal lethality.
