Co-immunoprecipitation and Western Blot analyses of SSG-1 interacting proteins. Whole cell free extracts of S. cerevisiae cells expressing the complete c-myc tagged SSG-1 coding sequence fused to the GAL4 activation domain (bait protein) and the HA tagged protein fragment fused to the GAL4 DNA binding domain (prey protein) were co-immunoprecipitated as described in Methods. The co-immuneprecipitated proteins were separated using 10% SDS polyacrylamide electrophoresis and transferred to nitrocellulose. The nitrocellulose strips were probed with anti-cMyc antibodies (Lane 1) and anti HA antibodies (Lane 3). Pre-stained molecular weight markers were included in outside lanes of the gel. The position of the molecular weight markers is indicated in the figure. Lanes 2 and 4 are negative controls where no primary antibody was added. Figure 7A corresponds to the results of the Co-IP of SSG-1 and SsSOD, Figure 7B corresponds to the results of the Co-IP of SSG-1 and SsNramp, Figure 7C corresponds to the results of the Co-IP of SSG-1 and SsSit and Figure 7D corresponds to the results of the Co-IP of SSG-1 and SsGAPDH.
