CC   -!- FUNCTION: Regulator of Notch signaling, a signaling pathway involved in
CC       cell-cell communications that regulates a broad spectrum of cell-fate
CC       determinations. Probably acts both as a positive and negative regulator
CC       of Notch, depending on the developmental and cell context. Functions as
CC       a ubiquitin ligase protein in vitro, suggesting that it may regulate
CC       the Notch pathway via some ubiquitin ligase activity. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC         [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC         cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC         EC=2.3.2.27; Evidence={ECO:0000250|UniProtKB:Q61010};
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC   -!- SUBUNIT: Homodimer. May form a heterodimer with other members of the
CC       Deltex family. Interacts with NOTCH1. {ECO:0000250|UniProtKB:Q80V91}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the Deltex family. {ECO:0000305}.
