Predicted to act upstream of or within neuron maturation; retinal bipolar neuron differentiation; and visual perception. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in corneal dystrophy; keratoconus; and posterior polymorphous corneal dystrophy 1. Orthologous to human VSX1 (visual system homeobox 1).
