dwg | Deformed wings (dwg) encodes an architectural chromatin protein essential for embryonic development that organizes open chromatin in regulatory regions (predominantly promoters). dwg product binding site was found in the insulator encoded by scs, and its functions include enhancer blocking, support of distant interactions and recruitment of transcription factors.

Gen | Flap endonuclease GEN; Endonuclease which cleaves flap structures at the junction between single-stranded DNA and double-stranded DNA. Specific for 5'- overhanging flap structures in which the 5'-upstream of the flap is completely double-stranded. Prefers the blocked-flap structures similar to those occurring at replication forks, in which the 5' single-strand overhang of the flap is double-stranded. Also possesses weak 5'- to 3'- exonuclease activity on nicked but not gapped double-stranded DNA. Does not cleave bubble-like or Holliday junction substrates. (726 aa) |
