Protein attributes

Sequence length	730 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Transcriptional corepressor that regulates transcription when recruited to specific target DNA by hairy-related bHLH proteins. Maternally required for neurogenesis; in the segregation of the neuroectoderm. Directly or indirectly interacts with Notch and Delta.
Subunit structure	Forms a complex with the hairy/Enhancer of split/deadpan family of basic helix-loop-helix proteins in order to repress transcription. Its activity in regulating transcription depends on other proteins as it lacks a DNA-binding motif.
Subcellular location	Nucleus.
Developmental stage	Expressed both maternally and zygotically.
Sequence similarities	Belongs to the WD repeat Groucho/TLE family. Contains 7 WD repeats.
