CC   -!- FUNCTION: Sequence-specific transcription factor that binds gene
CC       promoters and activates their transcription. Part of a developmental
CC       regulatory system that provides cells with specific positional
CC       identities on the anterior-posterior axis.
CC       {ECO:0000250|UniProtKB:P35453}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P70217}.
CC   -!- SIMILARITY: Belongs to the Abd-B homeobox family. {ECO:0000305}.
