USP7 co-localizes with TAL1, E2A, and HEB in the Jurkat cell line. (A) Density heatmap showing that the majority of the peaks from TAL1, E2A, and HEB ChIP-seq overlap with those of USP7. (B) Representative TAL1, HEB, E2A, and USP7 peaks proximal to the CD69 gene body. (C) Representative TAL1, HEB, E2A, and USP7 peaks proximal to the RAG1/2 gene body. (D) Affinity purification-mass spectrometry using USP7 and TAL1 as bait proteins. Venn diagram (left) shows the overlap of USP7 and TAL1 interacting proteins. P-value was calculated based on a two-sided Fishers-exact test. Spectral counts of USP7 and TAL1 interacting proteins are shown on the right. (E) Serial co-IP Western blotting showing the interaction of USP7/TAL1 and E proteins.
