Native top-down proteomics reveals EGFR-ERα signaling crosstalk in breast cancer cells dissociates NUTF2 dimers to modulate ERα signaling and cell growth.

Oligomerization of proteins and their modified forms (proteoforms) produces functional protein complexes . Complexoforms are complexes that consist of the same set of proteins with different proteoforms . The ability to characterize these assemblies within cells is critical to understanding the molecular mechanisms involved in disease and to designing effective drugs.
