Binding of Sec1p to SNARE complexes in sec mutant strains. (a) Coimmunoprecipitation of Sec1p and Sncp with HA-Sso2p. Wild-type and sec mutant strains expressing HA-Sso2p and an untagged wild-type control were grown at 25°C and shifted to 37°C for 10 min. Sec1p and Sncp coprecipitating with HA-Sso2p in anti-HA immunoprecipitates were observed by Western blotting. Note that the strains in this experiment were shifted to 37°C rather than to 38°C as in Fig. 2. This lower temperature is partially permissive for SNARE complex assembly in the sec8-6 mutant strain. (b) Coimmunoprecipitation of Ssop with myc-Sec1p and Sncp. Wild-type and sec mutant strains expressing myc-Sec1p and an untagged wild-type control were grown at 25°C and shifted to 37°C for 10 min. Ssop coprecipitating with myc-Sec1p in anti-myc immunoprecipitates and coimmunoprecipitating with Sncp in anti-Sncp precipitates was observed by Western blotting.
