Rare 'ambidextrous' protein breaks rules of handedness
Scientists discovered an ambidextrous protein that can function in both left-handed and right-handed forms, potentially reflecting early life based on mirror-image molecules.
Ku limits RNA-induced innate immunity to allow Alu-expansion in primates
Although Ku is critical in human cells, it is surprisingly dispensable for murine development, indicating a complex evolutionary role in DNA repair and immunity.
