Pulldowns of MBP-tagged subunit C and Vph1NT with RAVE and RAVE–V1.A, gel filtration fractions containing RAVE–V1 or RAVE were incubated with MBP-C and anti-FLAG M2 beads as indicated, then transferred to a column for elution. All blots were loaded with input (I), flowthrough (F), wash (W), and fractions collected after addition of FLAG peptide to elute bound protein. MBP-C was also incubated with beads in the absence of FLAG-tagged RAVE as a control. B, RAVE–V1 was incubated with MBP-Vph1NT as described in A in the presence and absence of MBP-C as indicated. MBP-Vph1NT with no added RAVE–V1 is included as a control. MBP, maltose-binding protein; MBP-C, MBP-tagged subunit C; RAVE, Regulator of the H+-ATPase of Vacuoles and Endosomes; Vph1NT, N-terminal domain of Vo subunit Vph1.
