Figure 6. NleE binds to an N-terminal region in TAB2/3 for efficient recognition.
(A) Domain illustration of TAB3 and summary of NleE interaction with TAB3 truncations. Interaction strength is scored by the number of + (also see the related data in Figure S4). CUE, CUE ubiquitin binding domain; TBD, TAK1-binding domain; CC, coiled-coil domain; NZF, Nlp4-like zinc finger domain. (B) Yeast two-hybrid assay of NleE interaction with TAB3 truncations. Yeast strain AH109 was transformed with plasmid combinations as illustrated (bait+prey). Plasmid combinations resulting in a positive interaction are highlighted in red. (C) Co-immunoprecipitation interaction assay of NleE and TAB3 truncations in transfected 293T cells. Shown are immunoblots of anti-Flag immunoprecipitates (Flag IP) and total cell lysates (Input).
