Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis By similarity.
Subcellular location	NucleusBy similarity.
Developmental stage	First expressed at the 1-somite stage. At the 10-somite stage, weakly expressed in the paraxial mesoderm with an anterior expression limit at somite 1. At the 20-somite stage, expressed within the developing CNS with an anterior expression limit adjacent to the rhombomere 7/8 boundary.
Sequence similarities	Belongs to the Antp homeobox family. Deformed subfamily. Contains 1 homeobox DNA-binding domain.
