Enriching the Phosphoproteome with Results from the Other Screens

(A) Proteins that interact with CDK9 (pTEFb) and that become phosphorylated upon UV irradiation. Proteins are labeled increasingly blue with increasing phosphorylation. Proteins that scored in the RNAi screen, (squares with red border), interacted with RNAPII (small green spheres under name), interacted with CSB (red spheres), or became ubiquitylated upon UV irradiation (yellow “•Ub”) are indicated. Examples of CSB or RNAPII interactions that increased (black circle around spheres) or decreased (yellow circle around spheres) upon UV irradiation are also specified.

(B) As in (A), but for proteins that interact with SRPK1.
