Vam2/6p is required for trans-SNARE pairing. The formation of trans-SNARE pairs between vacuoles was assayed as described in Ungermann et al. 1998. Vacuoles from strains BJ3505nyv1Δ and DKY6281vam3Δ (100 μg each) were incubated together at 27°C (lanes 2–4) or on ice (lane 1) with cytosol and ATP for 30 min. Reactions were supplemented with control buffer (lanes 1 and 2), affinity-purified anti-Vam2p IgG (lane 3), or affinity-purified anti-Vam2p Fab fragment (lane 4). Protein complexes were analyzed by coimmunoprecipitation with protein A–immobilized antibodies to Vam3p, SDS-PAGE, and immunoblotting with antibodies to Vam3p and Nyv1p.
