Figure 6. Direct interactions between domains of GBF1 and ATGL.
A- Purified GST, GST-tagged ATGL(1–366) or GST-tagged ATGL(300–504) was bound to glutathione Sepharose beads, then incubated with E. coli lysates expressing the His-tagged DCB domain of GBF1. Eluted proteins were analyzed by Western blotting using His antibody. B- and C- The indicated His-tagged GBF1 domain expressed in E. coli was bound to Ni Sepharose 6 Fast Flow, then purified GST or the indicated GST-tagged domain of ATGL were incubated with the protein-bound beads. Eluted proteins were analyzed by Western blotting using GST antibody. B- The HDS1-His domain of GBF1 bound to Ni Sepharose beads. C- The His-tagged Sec7 domain of GBF1 bound to Ni Sepharose beads.
