Coimmunoprecipitation of HA-Pma1p with Lst1p and Sec24p. Vesicles were generated from lst1-null, HA-Pma1p containing SICs using either a mixture of 10 μg/ml each of Sec23/Lst1p and Sec23/24p (lanes 1) or 20 μg/ml Sec23/24p only (lanes 2). In lanes 3, a mixture of 10 μg/ml each of Sec23/Lst1p and Sec23/24p was used as in lanes 1, but wild-type SICs membranes, not expressing HA-tagged Pma1p, were used. Lanes 4 contained a mixture of the vesicles generated in reactions 2 and 3. After cross-linking, reactions were immunoprecipitated with anti-Lst1p or anti-Sec24p as indicated, and subjected to SDS-PAGE and immunoblot analysis using anti-HA antibodies. Input lanes represent 1% of the cross-linked reactions before immunoprecipitation.
