Figure Lengend Snippet: Inhibition of TRAP230 function in transfected COS-7 cells by the TRAP230-derived M40 fragment. Increasing amounts of the TRAP230/M40 fragment fused to HA tag (HA-M40) inhibit the transactivation capacity of GAL4-SOX9 TA-domain, whereas HA-M40 has no inhibitory effect on the transactivation capacity of GAL4-VP16. COS-7 cells were transfected with 10 ng of pBIND SOX9-TA-domain or pBIND VP16-TA-domain, 500 ng of GAL4-responsive luciferase reporter plasmid (5× UAS Luc) and either 10 or 20 ng of pcDNA HA-M40, or an empty vector pcDNA (20 ng). Luciferase values have been normalized to SOX9-TA mediated activation without pcDNA Ha-M40 but with an empty pcDNA taken as 100%, which corresponds to a 10–15-fold induction from one experiment to another. Results are expressed as percentage inhibition of the SOX9 TA-domain activity and represent the means of triplicate experiments performed six times.
Article Snippet: The SOX9 TA-domain (amino acids 408–509) was cloned into pBIND vector (Checkmate two-hybrid System; Promega), thus creating a fusion construct encoding both the yeast GAL4 DNA-binding domain and the SOX9 TA-domain.
