Small proteins, big impact: Why SUMO proteins are crucial for plant chromosomes
Phys.org • 12/9/2025 • Last cited 12/14/2025
Summary
A recent study highlights the importance of SUMO proteins in plant chromosomes, particularly in the function of the kinetochore protein complex at the centromere, which is essential for proper chromosome movement during cell division. According to Phys.org, KINETOCHORE NULL2 (αKNL2) is identified as a key protein in loading centromeric histone H3 (CENH3) onto centromeres and forming the kinetochore.
