NPC1 encodes a large protein that resides in the limiting membrane of endosomes and lysosomes and mediates intracellular cholesterol trafficking via binding of cholesterol to its N-terminal domain. Additionally we are shipping NPC1 Antibodies (67) and NPC1 Kits (6) and many more products for this protein.
Showing 6 out of 10 products:
this is the first report, showing a role of NPC1 in platelet function and formation but further studies are needed to define how cholesterol storage interferes with these processes
npc1 is required early for proper cell movement and cholesterol localization and later for cell survival
Availability of assays to measure NPC1 binding to membrne proteins may further the understanding of ways in which oxysterols regulate intracellular lipid transport.
Our data show that: i) HDAC2 (show HDAC2 Proteins) levels and activity are increased in NPC neuronal models and in Npc1(-/-) mice; ii) inhibition of c-Abl (show ABL1 Proteins) or c-Abl (show ABL1 Proteins) deficiency prevents the increase of HDAC2 (show HDAC2 Proteins) protein levels and activity in NPC neuronal models
This study showed that deleting the Npc1 gene is accompanied by an increase in germ cell apoptosis and compensatory imbalances in the expression of cholesterol enzymatic and transporter factors.
These results show that NPC1 is critical for ebolavirus replication and pathogenesis in animals.
abnormal neuronal expression of matrix metalloproteinase-12 (show MMP12 Proteins) may contribute to axonal degeneration in Niemann-Pick type C disease
There was a transient increase in biliary cholesterol concentration in Npc1(-/-) mice.
data suggest that aberrant expression of Pcdhs is a pathological process accompanied by neurodegeneration in Npc1 mutant mice
This study deministrated that lack of NPC1 in either neurons or glial cells did not affect the excitability of Purkinje cells, the formation of dendrites or their excitatory synaptic activity.
Hearing loss is an early consequence of Npc1 gene deletion in the mouse model of Niemann-Pick disease, type C.
These data show that cholesterol homeostasis through NPC1 plays a crucial role in maintaining insulin (show INS Proteins) action at multiple levels in adipocytes.
Data suggest that axonal pathologies in Npc1 mutant spinal cord are strongly correlated with the increase of activated glial cells, which produce IL-1beta (show IL1B Proteins) and ApoE (show APOE Proteins), resulting in activation of p38-MAPK (show MAPK14 Proteins) signaling pathway and enhanced phosphorylated tau protein
Fibroblasts from Niemann-Pick type C (NPC) disease patients with low levels of NPC1 protein have high amounts of procathepsin D but reduced quantities of the mature protein, thus showing a diminished cathepsin D (show CTSD Proteins) activity.
Results identified six novel mutations (PKHD1: p.Thr777Met, p.Tyr2260Cys; ABCB11 (show ABCB11 Proteins): p.Val1112Phe, c.611+1G > A, p.Gly628Trpfs*3 and NPC1: p.Glu391Lys) for the diagnostic of inherited infantile cholestatic disorders.
NPC1 mutations are substantially enriched in unexplained early onset ataxia (show USP14 Proteins), making it high risk group for Niemann-Pick disease type C.
these results clearly demonstrated that the over-expression of NPC1 with a defective function in an imatinib-resistant Ph+ acute lymphoblastic leukemia cell line
Structure of glycosylated NPC1 luminal domain C reveals insights into NPC2 (show NPC2 Proteins) and Ebola virus interactions
Study determined the crystal structure of the primed GP (GPcl) of Ebola virus bound to domain C of NPC1 (NPC1-C); NPC1-C utilizes two protruding loops to engage a hydrophobic cavity on head of GPcl. Upon enzymatic cleavage and NPC1-C binding, conformational change in the GPcl further affects the state of the internal fusion loop, triggering membrane fusion.
Here, using live cell imaging, the authors obtained evidence that in contrast to the new model, ebolavirus enters cells through endolysosomes that contain both NPC1 and TPC2 (show TPCN2 Proteins).
These experiments support a model in which NPC1 protein functions to transfer cholesterol past a lysosomal glycocalyx.
An isobaric labeling-based quantitative analysis of proteome of NPC1(I1061T) primary fibroblasts when compared with wild-type cells identified 281 differentially expressed proteins based on stringent data analysis criteria, is reported.
NPC1 gene sequencing revealed that he was a compound heterozygote for the p.S954L and p.N1156S mutations.
This gene encodes a large protein that resides in the limiting membrane of endosomes and lysosomes and mediates intracellular cholesterol trafficking via binding of cholesterol to its N-terminal domain. It is predicted to have a cytoplasmic C-terminus, 13 transmembrane domains, and 3 large loops in the lumen of the endosome - the last loop being at the N-terminus. This protein transports low-density lipoproteins to late endosomal/lysosomal compartments where they are hydrolized and released as free cholesterol. Defects in this gene cause Niemann-Pick type C disease, a rare autosomal recessive neurodegenerative disorder characterized by over accumulation of cholesterol and glycosphingolipids in late endosomal/lysosomal compartments.
