Figure 5. Disease-causing deletional mutants of TRAPPC9 fail to bind to TRAPPC2 or TRAPPC10.

Figure 5

A. GFP -GAP273, -TRAPPC9, -TRAPPC9(L772Δ) and -TRAPPC9(R475X) were tested for the interaction with Myc-tagged TRAPPC2. The levels of protein expression in the transfected lysates are shown in lanes 1 to 4. Lanes 5 to 8 are immunoprecipitants. Full-length TRAPPC9 was efficiently pulled down by Myc-TRAPPC2 (lane 6), but not the deletion mutants of TRAPPC9 (lane 7 and 8), or negative control GFP-GAP273 (lane 5). B. Full-length and deletional mutants of TRAPPC9 were tested for the interaction with Myc-tagged TRAPPC10. The levels of protein expression in the transfected lysates are shown in lanes 1 to 4. Lanes 5 to 8 are immunoprecipitants. Full-length TRAPPC9 was efficiently pulled down by Myc-TRAPPC10 (lane 6), but not the deletional mutants (lane 7 and 8), or negative control GFP-GAP273 (lane 5). The experiments shown are representatives of two independent experiments.
