Self-association of ZNF198–FGFR1.

The 4 and 10 zinc finger ZNF198–FGFR1 isoforms were tagged with HA or MYC, expressed individually (lanes 2, 3, 5, and 6) or coexpressed (lanes 4 and 7) in 293 T cells, then immunoprecipitated and detected with anti-HA or anti-MYC. Empty pcDNA 3 vector was also transfected as a negative control. Both 4 and 10 zinc finger ZNF198–FGFR1 isoforms self-associate (lanes 4 and 7).
