CC   -!- FUNCTION: Sequence-specific transcription factor which is part of a
CC       developmental regulatory system that provides cells with specific
CC       positional identities on the anterior-posterior axis. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the Abd-B homeobox family. {ECO:0000305}.
