Proximity Label-MS

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.

Interrogating the protein interactomes of RAS isoforms identifies PIP5K1A as a KRAS-specific vulnerability.

Adhikari H, Counter CM

In human cancers, oncogenic mutations commonly occur in the RAS genes KRAS, NRAS, or HRAS, but there are no clinical RAS inhibitors. Mutations are more prevalent in KRAS, possibly suggesting a unique oncogenic activity mediated by KRAS-specific interaction partners, which might be targeted. Here, we determine the specific protein interactomes of each RAS isoform by BirA proximity-dependent biotin identification. The ... [more]
