Expressioni

Tissue specificityi

In the adult, expressed exclusively in the cells of the neural retina with expression restricted to postnatal cone bipolar interneurons.

Developmental stagei

Expressed at P5, solely within the inner nuclear layer (INL) of the central neuroretina. By days P6 and P7, expression expands peripherally during neurogenesis. By P12, expression is restricted to the outer margin of the INL and reaches the outer periphery of the neuroretina.
