Protein attributes

Sequence length	399 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein 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. Binds to the DNA sequence 5'-AA[AT]TTTTATTAC-3'.
Subcellular location	Nucleus.
Tissue specificity	Expressed in the developing limb bud where it is restricted to the mesenchyme along the proximal-distal axis. Also found in developing gut and urogenital tract. In adult tissue, both forms found in kidney but only isoform 1 is expressed in skeletal muscle.
Developmental stage	Embryonic expression increases from day 9 to day 12 and then declines to day 15.
Sequence similarities	Belongs to the Abd-B homeobox family. Contains 1 homeobox DNA-binding domain.
