Recombinant Human Non-specific lipid-transfer protein (SCP2)

1. We (1) analyzed the structural basis of the fold and the classification of SCP2 domains; (2) identified structure-determined sequence features; (3) compared the lipid binding cavity of SCP2 and other lipid binding proteins; (4) surveyed proposed mechanisms of SCP2 mediated lipid transfer between membranes; and (5) uncovered a possible new function of the SCP2 domain as a protein-protein recognition device. PMID: 28284963
2. imported protein sterol carrier protein 2 (SCP2) occupies only a subregion of larger peroxisomes, highlighting the heterogeneous distribution of proteins even within the peroxisome. PMID: 27311714
3. Mice harboring a deletion of the Scp2 locus present a modulated diurnal accumulation of lipids in the liver and a perturbed activation of several signaling pathways including PPARalpha, SREBP, LRH-1, TORC1 and its upstream regulators. PMID: 27097688
4. We conclude that SCP-2 is a low affinity binding protein for arachidonylethanolamine that can facilitate its cellular uptake but does not contribute significantly to intracellular sequestration of AEA. PMID: 24510313
5. cellular SCP-2 not only binds and translocates cholesterol but also cholesterol hydroperoxides, thus expanding their redox toxicity and signaling ranges under oxidative stress conditions PMID: 20656919
6. Statistical analysis indicated that six genes, NFATC2, SCP2, CACNA1C, TCRA, POLE, and FAM3D, were associated with narcolepsy. PMID: 20677014
7. data for the first time showed that while the N-terminal membrane binding domain of SCP(2) was itself inactive in mediating intermembrane sterol transfer, it nevertheless potentiated the ability of SCP(2) to enhance sterol transfer PMID: 12356316
8. plays a hitherto unrecognized role in intracellular phosphatidylinositol transfer, distribution, and signaling PMID: 12641450
9. SCP2 in the cellular defense against oxidative damage and found that a fluorescent fatty acid analog bound to SCP2 is protected against H2O2/Cu2+-induced oxidative damage PMID: 14563822
10. Overexpression of human SCP-2 in murine fibroblasts significantly alters the sterol dynamics of caveolae/lipid rafts, but not nonlipid raft domains, to facilitate retention of cholesterol within the cell. PMID: 14661971
11. By trafficking cholesterol hydroperoxides and phospholipid hydroperoxides in addition to parent lipids, SCP2 may exacerbate cell injury under oxidative stress conditions PMID: 15449949
12. Long chain fatty acyl-coenzyme A (CoA)s are confirmed to be high affinity ligands for SCP2, while long chain fatty acyl-carnitines are demonstrated for the first time not to interact with SCP2. PMID: 17418802
13. the importance of the N-terminal presequence in regulating SCP-2 structure, cholesterol localization within the ligand binding site, membrane association, and, potentially, intracellular targeting PMID: 18465878
14. Results describe the dynamical effect of sterol carrier protein-2 (SCP-2) interacting between aqueous dispersions of dehydroergosterol monohydrate microcrystal donors and acceptors. PMID: 19020914
