Using AI to keep CRISPR technology in-check
Last year, a ten-month-old baby in the US was the first person in the world to have their rare genetic disease effectively cured through the use of CRISPR gene editing technology. But the rollout of CRISPR across a wide range of genetic…

Cryo-EM structures reveal conformational dynamics behind AP-4 membrane trafficking
Adaptor protein (AP) complexes play central roles in intracellular vesicular trafficking by coupling cargo selection to vesicle formation. AP-4, an important member of the AP family, plays a key role in this process. AP-4 dysfunction disrupts the…
