MGI Phenotype

FUNCTION: This gene encodes a member of the cysteine peptidase family C13 that plays an important role in the endosome/lysosomal degradation system. The encoded inactive preproprotein undergoes autocatalytic removal of the C-terminal inhibitory propeptide to generate the active endopeptidase that cleaves protein substrates on the C-terminal side of asparagine residues. Mice lacking the encoded protein exhibit defects in the lysosomal processing of proteins resulting in their accumulation in the lysosomes, and develop symptoms resembling hemophagocytic lymphohistiocytosis. [provided by RefSeq, Aug 2016]
PHENOTYPE: Homozygotes for a null allele exhibit slow postnatal weight gain, develop features of hemophagocytic syndrome, and accumulate giant lysosomes in renal tubule cells. Homozygotes for another null allele display impaired TLR9 signaling in dendritic cells, progressive kidney pathology, and proteinuria. [provided by MGI curators]
