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.

       ab218192 Anti-Niemann Pick C2 antibody [EPR19993-145-1] was shown to specifically react with Niemann Pick C2 in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab266749 (knockout cell lysate ab258079) was used. Wild-type and Niemann Pick C2 knockout samples were subjected to SDS-PAGE. ab218192 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
