CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108,
CC       ECO:0000255|PROSITE-ProRule:PRU00138}.
CC   -!- MISCELLANEOUS: In contrast to its counterpart in Heliocidaris
CC       tuberculata, not involved in larval skeletal patterning.
CC   -!- SIMILARITY: Belongs to the paired homeobox family. Bicoid subfamily.
