CC -!- FUNCTION: Transcription factor that functions as a master developmental
CC regulator controlling midline development of the ventral nerve cord.
CC Required to correctly specify the formation of the central brain
CC complex, which controls walking behavior. Also required for correct
CC patterning of the embryonic genital disk and anal pad anlage. Plays a
CC role in synapse development. {ECO:0000269|PubMed:12221007,
CC ECO:0000269|PubMed:23644463, ECO:0000269|PubMed:9840810}.
CC -!- SUBUNIT: Efficient DNA binding requires dimerization with another bHLH
CC protein.
CC -!- INTERACTION:
CC P05709; O15945: tgo; NbExp=3; IntAct=EBI-88929, EBI-172695;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00981}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=A;
CC IsoId=P05709-1; Sequence=Displayed;
CC Name=B;
CC IsoId=P05709-2; Sequence=VSP_011812;
CC -!- TISSUE SPECIFICITY: Embryonic nerve cord.
CC {ECO:0000269|PubMed:12221007}.
CC -!- POLYMORPHISM: Berkeley strain has 11 A-A-Q repeats.
CC {ECO:0000269|PubMed:1760843}.
CC -!- MISCELLANEOUS: Mutations result in the loss of the precursor cells that
CC give rise to midline cells of the embryonic central nervous system.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAC64519.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
