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. Binds to sites in
CC       the 5'-flanking sequence of its coding region with various affinities.
CC       The consensus sequences of the high and low affinity binding sites are
CC       5'-TAATGA[CG]-3' and 5'-CTAATTTT-3'.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the Antp homeobox family. Deformed subfamily.
CC       {ECO:0000305}.
