CC   -!- FUNCTION: Transcription factor, which is involved in craniofacial
CC       development, in odontogenesis and in stomach organogenesis. May have a
CC       role in the differentiation of molars from incisors. Plays a role in
CC       suppressing endodermal Wnt activity (By similarity). Binds to a
CC       regulatory module of the NCAM promoter. {ECO:0000250,
CC       ECO:0000269|PubMed:9804553}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=2;
CC       Name=1;
CC         IsoId=Q9HBU1-1; Sequence=Displayed;
CC       Name=2;
CC         IsoId=Q9HBU1-2; Sequence=VSP_034700;
CC   -!- TISSUE SPECIFICITY: Widely expressed. Expressed at higher levels in
CC       testis and heart. Detected in craniofacial tissue and adult iris, but
CC       not in lymphocytes, fibroblasts, choroid retina, retinal pigment
CC       epithelium, kidney, or fetal liver.
CC   -!- POLYMORPHISM: The polymorphism is not associated with Axenfeld-Reiger
CC       syndrome (ARS), iridogoniodysgenesis syndrome (IGDS) or related ocular
CC       malformations. {ECO:0000305|PubMed:10995576}.
CC   -!- SIMILARITY: Belongs to the BAR homeobox family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAG23738.1; Type=Frameshift; Evidence={ECO:0000305};
