  • Figure S1: Analysis of FHA domain-Dbf4 interactions including a screen of all Y residues in Dbf4 residues 100-227 (PDF, 2 MB)
  • Figure S2: Dbf4 residues V104, T105, E108, L109, and W112 were required for binding the Rad53 FHA domains. (PDF, 1 MB)
  • Figure S3: Dbf4 residues V104, E108, and L109 were critical for binding the Rad53 FHA domains. (PDF, 477 KB)
  • Figure S4: The synthetic lethality between dbf4-Ndelta109 and rad53-1 or rad53delta was not due to either loss of Cdc5 interaction or increased Dbf4 stability, but requires sequences between residues 82-109. (PDF, 1 MB)
