Table II. RAD6A XLID mutations disrupt specific protein-protein interactions. Flag-tagged RAD6A WT and mutant proteins (R7W, R11Q) were expressed in 293 T-REx cells, and interacting proteins identified via AP-MS, as above. Each column lists maximum spectral counts from two technical runs for each cell pool. Interactions maintained (blue) or lost (grey) in the mutant proteins are indicated.
