Protein attributes

Sequence length	205 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Transcriptional repressor of genes that require a bHLH protein for their transcription. May serve as a transcriptional regulator of the Achaete-scute complex (AS-C) genes. Contributes to the neural-epidermal lineage decision during early neurogenesis. Part of the Notch signaling pathway.
Subunit structure	Transcription repression requires formation of a complex with a corepressor protein (Groucho) By similarity.
Subcellular location	Nucleus Probable.
Tissue specificity	Expressed in sensory organ precursors in the wing, leg and eye imaginal disk. Ref.3
Domain	Has a particular type of basic domain (presence of a helix-interrupting proline) that binds to the N-box (CACNAG), rather than the canonical E-box (CANNTG). The C-terminal WRPW motif is a transcriptional repression domain necessary for the interaction with Groucho, a transcriptional corepressor recruited to specific target DNA by Hairy-related proteins.
Sequence similarities	Contains 1 basic helix-loop-helix (bHLH) domain. Contains 1 Orange domain.
