Previous GeneCards Identifiers for NPC2 Gene
This gene encodes a protein containing a lipid recognition domain. The encoded protein may function in regulating the transport of cholesterol through the late endosomal/lysosomal system. Mutations in this gene have been associated with Niemann-Pick disease, type C2 and frontal lobe atrophy. [provided by RefSeq, Jul 2008]
GeneCards Summary for NPC2 Gene
NPC2 (NPC Intracellular Cholesterol Transporter 2) is a Protein Coding gene. Diseases associated with NPC2 include Niemann-Pick Disease, Type C2 and Niemann-Pick Disease Type C, Severe Early Infantile Neurologic Onset. Among its related pathways are Innate Immune System and Cholesterol and Sphingolipids transport / Distribution to the intracellular membrane compartments (normal and CF). GO annotations related to this gene include enzyme binding and cholesterol binding.
UniProtKB/Swiss-Prot for NPC2 Gene
Intracellular cholesterol transporter which acts in concert with NPC1 and plays an important role in the egress of cholesterol from the endosomal/lysosomal compartment. Both NPC1 and NPC2 function as the cellular tag team duo (TTD) to catalyze the mobilization of cholesterol within the multivesicular environment of the late endosome (LE) to effect egress through the limiting bilayer of the LE. NPC2 binds unesterified cholesterol that has been released from LDLs in the lumen of the late endosomes/lysosomes and transfers it to the cholesterol-binding pocket of the N-terminal domain of NPC1. Cholesterol binds to NPC1 with the hydroxyl group buried in the binding pocket and is exported from the limiting membrane of late endosomes/ lysosomes to the ER and plasma membrane by an unknown mechanism. The secreted form of NCP2 regulates biliary cholesterol secretion via stimulation of ABCG5/ABCG8-mediated cholesterol transport.
