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.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- DEVELOPMENTAL STAGE: Embryo.
CC   -!- SIMILARITY: Belongs to the Antp homeobox family. {ECO:0000305}.
