CC -!- FUNCTION: DNA-binding protein that binds to the 5'-CAAG-3' core
CC sequence. May function as a transcriptional repressor. Seems to act as
CC a transcriptional antagonist of NKX2-5. May play an important role in
CC the development of craniofacial structures such as the eye and ear.
CC {ECO:0000269|PubMed:10206974}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- DISEASE: Oculoauricular syndrome (OCACS) [MIM:612109]: A syndrome
CC characterized by microphthalmia, microcornea, anterior segment
CC dysgenesis, cataract, ocular coloboma, retinal pigment epithelium
CC abnormalities, rod-cone dystrophy, and anomalies of the external ear.
CC {ECO:0000269|PubMed:18423520}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the HMX homeobox family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF70205.1; Type=Frameshift; Evidence={ECO:0000305};
