Biological background
Biological context: Intracellular cholesterol transporter which acts in concert with NPC1 and plays an important role in the egress of cholesterol from the lysosomal compartment. Unesterified cholesterol that has been released from LDLs in the lumen of the late endosomes/lysosomes is transferred by NPC2 to the cholesterol-binding pocket in the N-terminal domain of NPC1. May bind and mobilize cholesterol that is associated with membranes. NPC2 binds cholesterol with a 1:1 stoichiometry. Can bind a variety of sterols, including lathosterol, desmosterol and the plant sterols stigmasterol and beta-sitosterol. The secreted form of NCP2 regulates biliary cholesterol secretion via stimulation of ABCG5/ABCG8-mediated cholesterol transport.
Expression and localization notes: cellular localization: Secreted. Endoplasmic reticulum. Lysosome., tissue context: Ubiquitously expressed..
Common research applications
- Western blotting (WB): Compare NPC2 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of NPC2 in tissue sections, considering fixation and antigen retrieval effects.
- Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
- Flow cytometry: Quantify NPC2-positive populations in single-cell suspensions with appropriate gating and controls.
- ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.
Notes for experimental interpretation
- Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
- Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.
Additional product notes (from provided fields)
- Specificity: No cross reactivity with other proteins.
- Background: Epididymal secretory protein E1 (also called NPC intracellular cholesterol transporter 2, or NPC2) is a protein associated with Niemann-Pick disease, type C. It is mapped to 14q24.3. 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.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Secreted. Endoplasmic reticulum. Lysosome.
- Tissue details: Ubiquitously expressed.
