Description

Xingyu Chen and co-authors report a 2024 chemistry tool for catching proteins in the act of touching. Mapping protein partnerships inside living cells is hard because common cross-linkers leak poorly through cell walls and waste themselves on water. The team built a cross-linker caged by light-sensitive groups that keep it stable and fat-friendly until a flash of ultraviolet frees it.

Once freed, the linker grabs nearby amino groups and locks the bond with a follow-up step. On a test protein, the tool reliably flagged known partnerships under mass spectrometry. It also slipped into intact HeLa cells, which points to future use for mapping partnerships in their true home.
