Interaction between AtVAM3 and AtVTI11. (A) Extract from
zig-1/pSCR::T7-ZIG plants was immunoprecipitated
with anti-T7 monoclonal antibody (Left) or anti-AtVAM3 antiserum
(Right), and then probed with the antibody or antisera indicated to
the left. (B) Total extracts from wild-type (lane 1),
sgr3-1/- homozygous (lane 2), and sgr3-1/+
heterozygous (lane 3) plants were probed with anti-AtVAM3 antiserum.
(C) Interaction between mutant AtVAM3 protein and partner SNAREs.
Extract from sgr3-1/+
zig-1/pSCR::T7-ZIG was immunoprecipitated with
anti-T7 antibody or anti-SYP5 antiserum and then probed with anti-AtVAM3
antiserum. (D) A mixture of sgr3-1
zig-1/pSCR::T7-ZIG and zig-1 homozygous plant
extracts was immunoprecipitated with anti-T7 antibody and then probed with
anti-AtVAM3 antiserum. T, total protein extract; S, supernatant; IP,
immunoprecipitate. The arrowhead and asterisk indicate wild-type and mutant
AtVAM3 protein, respectively.
