Description
Description
The heterotrimeric insulator complex ELBA is a chromatin boundary factor, which binds to specific DNA and confers insulator activity during early embryogenesis. (Adapted from FBrf0227658 and FBrf0221291).
Notes on Group

ELBA has been shown to bind an element within the Bithorax Complex Fab-7 boundary element (FBrf0221291).
