摘要
A chemoproteomic-driven approach was used to investigate the interaction network between human telomeric G-quadruplex DNA and nuclear proteins. We identified novel G-quadruplex binding partners, able to recognize these DNA structures at chromosome ends, suggesting a possible, and so far unknown, role of these proteins in telomere functions.
