Homeobox protein SIX1 is a protein that in humans is encoded by the SIX1 gene.The vertebrate SIX genes are homologs of the Drosophila ‘sine oculis’ (so) gene which is expressed primarily in the developing visual system of the fly. Members of the SIX gene family encode proteins that are characterized by a divergent DNA-binding homeodomain and an upstream SIX domain which may be involved both in determining DNA-binding specificity and in mediating protein-protein interactions.
