Gene Snapshot

pita (pita) encodes an architectural chromatin protein essential for embryonic development that organizes open chromatin in the regulatory regions (predominantly promoters). pita product functions include enhancer blocking, support of distant interactions, protection from spreading of repressed chromatin and recruitment of transcription factors.

C2H2 ZINC FINGER TRANSCRIPTION FACTORS -: Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys₂His₂ zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).

Summary (Interactive Fly)
