RT   "The expression of rat homeobox-containing genes is developmentally
RT   regulated and tissue specific.";
RL   Development 103:601-610(1988).
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   -!- SUBUNIT: Forms a DNA-binding heterodimer with transcription factor
CC       PBX1. {ECO:0000250|UniProtKB:P17481}.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- TISSUE SPECIFICITY: Predominantly spinal cord and kidney.
CC   -!- SIMILARITY: Belongs to the Antp homeobox family. {ECO:0000305}.
