Target

  • Function

    May be involved in the regulation of the lipid composition of sperm membranes during the maturation in the epididymis.
  • Tissue specificity

    Epididymis.
  • Involvement in disease

    Defects in NPC2 are the cause of Niemann-Pick disease type C2 (NPDC2) [MIM:607625]. A lysosomal storage disorder that affects the viscera and the central nervous system. It is due to defective intracellular processing and transport of low-density lipoprotein derived cholesterol. It causes accumulation of cholesterol in lysosomes, with delayed induction of cholesterol homeostatic reactions. Niemann-Pick disease type C2 has a highly variable clinical phenotype. Clinical features include variable hepatosplenomegaly and severe progressive neurological dysfunction such as ataxia, dystonia and dementia. The age of onset can vary from infancy to late adulthood.
  • Sequence similarities

    Belongs to the NPC2 family.
  • Cellular localization

  • Immunohistochemical analysis of paraffin-embedded human endometrium cancer tissue labeling Niemann Pick C2 with ab207158 at 1/4000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasmic staining on human endometrium cancer is observed. Counter stained with Hematoxylin.
