Summary

Story summary

A study from the Institute of Science Tokyo shows the FUS protein utilizes zinc finger (ZnF) domains and intrinsically disordered regions (IDR) for RNA binding.
The combination of ZnF and IDR increases binding strength, nearly tenfold compared to ZnF alone.
The findings indicate IDRs play a significant role in RNA binding, influencing gene regulation and drug design.
Future research will explore this mechanism in other RNA-related proteins and the impact of post-translational modifications.
