Gene Type: protein_coding_gene
Location: Chr: 16 Mapping Details/Browsers
Description: Predicted to have DNA-binding transcription repressor activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Involved in pronephric nephron tubule epithelial cell differentiation and retina morphogenesis in camera-type eye. Predicted to localize to nucleus. Is expressed in several structures, including basal plate midbrain region; nervous system; otic vesicle; pectoral fin bud; and pronephric tubule. Orthologous to human IRX2 (iroquois homeobox 2).
