PMID Gene Context Sentence
32457038 The NP-C disease-causing gene (NPC1) has been strongly associated with viral infection, as a filovirus receptor (e.g., Ebola) and through LE/L lipid trafficking. […] This suggests NPC1 inhibitors or NP-C disease mimetics could serve as anti-SARS-CoV-2 agents. […] Inhibition of NPC1 may impair viral SARS-CoV-2 infectivity via several lipid-dependent mechanisms, which disturb the microenvironment optimum for viral infectivity. […] We suggest that known mechanistic information on NPC1 could be utilized to identify existing and future drugs to treat COVID-19.
32660402 Genomic variants in NPC1, which encodes for the endolysosomal Niemann-Pick type C1 protein, restricts the host-range of viruses in bats and susceptibility to infections in humans. […] Lack of NPC1 and its pharmacological suppression inhibits many viral infections including SARS-CoV-1 and Type I Feline Coronavirus Infection. […] Antiviral effects of NPC1-inhibiting drugs for COVID-19 treatment should be explored.
32880929 The lysosomal membrane protein NPC1 (Niemann-Pick type C1) and NPC2 (Niemann-Pick type C2) are main players of cholesterol control in the lysosome and it is known that the mutation on these proteins leads to the cholesterol trafficking related neurodegenerative disease, which is called the Niemann-Pick disease type C (NPC) disease. […] The mutation R518W or R518Q on the NPC1 is one of type of disease-related mutation that causes cholesterol transports to be cut in half, which results in the accumulation of cholesterol and lipids in the late endosomal/lysosomal compartment of the cell. […] Even though there has been significant progress with understanding the cholesterol transport by NPC1 in combination with NPC2, especially after the structural determination of the full length NPC1 in 2016, many details such as the interaction of the full length NPC1 with the NPC2, the molecular motions responsible for the cholesterol transport during and after this interaction, and the structure and the function relations of many mutations are still not well understood. […] In this paper, we report the extensive molecular dynamics simulations in order to gain insight into the structure and the dynamics of NPC1 lumenal domain for the cholesterol transport and the disease behind the mutation (R518W). […] It was found that the mutation induces a structural shift of the NTD (N-terminal domain), toward the loop region in the MLD (middle lumenal domain), which is believed to play a central role in the interaction with NPC2 protein, so the interaction with the NPC2 protein might be less favorable compared to the wild NPC1. […] Also, the simulation indicates the possible re-orientation of the NTD with both the wild and the R518W mutated NPC1 after receiving the cholesterol from the NPC2, that align to form an internal tunnel, which is a possible pose for further action in cholesterol trafficking. […] We believe the current study can provide a better understanding of the cholesterol transport by NPC1 especially the role of NTD of NPC1 in combination with NPC2 interactions.
33159981 Interestingly, numerous virus infection required NPC1 as well as ORPs along the endocytic pathway.
33211371 Using a NPC1-pHluorin2 reporter cell line, we confirmed that AZ treatment could alkalize the vesicles containing IAV virions, thereby preventing pH-dependent membrane fusion.
