Protein existence	Evidence at protein level

General annotation (Comments)

Function	Transcriptional repressor that plays an important role in the specification and differentiation of lung epithelium. Can act with CTBP1 to synergistically repress transcription but CTPBP1 is not essential. Essential transcriptional regulator of B-cell development. Ref.5 Ref.6
Subunit structure	Forms homodimers and heterodimers with FOXP2 and FOXP4. Dimerization is required for DNA-binding. Interacts with CTBP1. Ref.5
Subcellular location	Nucleus Probable.
Tissue specificity	Highest expression in the lung, brain, and spleen. Lower expression in heart, skeletal muscle, kidney, small intestine (isoform 3 not present) and liver.
Developmental stage	Expressed in developing lung, neural, intestinal and cardiovascular tissues. Expressed in both the airway epithelium of the forming lung as well as in the surrounding mesenchyme. By 16.5 dpc, expressed throughout the conducting airway epithelium, with highest expression in the distal alveolar regions. Also expressed in the endotheial cells of the pulmonary vasculature. During intestinal development, expressed in the mucosal layer but absent from the epithelium at 12.5 dpc. By 16.5 dpc, expressed in both the inner circular and outer longitudinal muscular layers of the intestine as well as in the epithelium of the intestine and developing stomach. Ref.4
Domain	The leucine-zipper is required for dimerization and transcriptional repression. Ref.5
Sequence similarities	Contains 1 C2H2-type zinc finger. Contains 1 fork-head DNA-binding domain.
