Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Lysetem2Janc mutation (0 available); any Lyset mutation (5 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
homeostasis/metabolism
• serum shows higher enzyme activities of all tested lysosomal enzymes including alpha-mannosidase, beta-hexosaminidase, alpha-L-fucosidase, and beta-galactosidase
• however, mice do not show obvious clinical symptoms observed in humans with TMEM251 mutations

cellular
• mouse embryonic fibroblasts (MEFs) show morphological changes in lysosomes including accumulation of electron dense material in the cytoplasm indicating storage materials in lysosomes
• MEFs show more numerous and larger lysosomes, however cell area is not altered

immune system
• MEFs are resistant to infection by a GFP-encoding vesicular stomatitis virus pseudotyped with the Ebola virus glycoprotein (VSV-EBOV-GP)
