Abstract:ABC50 (aka ABCF1) is a member of the ATP Binding Cassette protein family. ABC50 stimulates complex formation between eIF2, GTP and Met-tRNA implicating it in translation initiation. Econazole (Ec) is an imidazole anti-fungal that induces endoplasmic reticulum (ER) stress in mammalian cells by promoting ER Ca(2+) depletion and sustained protein synthesis inhibition. HL60 cells selected for Ec resistance were found to exhibit a multi-drug resistance phenotype associated specifically with ER stress. Differential …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
