Expressioni

Tissue specificityi

In embryos at the neural fold stage, localized primarily in the anterior neural plate, and localized mostly in the anterior region of the nerve cord of neurula stage embryos. In tailbud stages, expressed predominantly in the eye and brain, with weak expression along the length of the nerve cord. In adults, expressed in skin and brain.1 Publication

Developmental stagei

Embryonic expression begins at the neural plate stage and continues throughout development to adulthood.1 Publication
