KRAS is a small GTPase that regulates cell proliferation. Here, the authors show that a subset of cell surface glycosphingolipids regulate KRAS plasma membrane localization by modulating inner leaflet lipid composition, uncovering a requirement for KRAS oncogenesis that may have therapeutic potential.

Left-handed Z-DNA/Z-RNA is bound with high affinity by the Zα domain protein family that includes ADAR (a double-stranded RNA editing enzyme), ZBP1 and viral orthologs regulating innate immunity. Loss-of-function mutations in ADAR p150 allow persistent activation of the interferon system by Alu dsRNAs and are causal for Aicardi-Goutières Syndrome. Heterodimers of ADAR and DICER1 regulate the switch from RNA- to protein-centric immunity. Loss of DICER1 function produces age-related macular degeneration, a different type of Alu-mediated disease. The overlap of Z-forming sites with those for the signal recognition particle likely limits invasion of primate genomes by Alu retrotransposons. Show less
