Acts upstream of or within cornea development in camera-type eye. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including central nervous system; cranial muscle; jaw; limb mesenchyme; and sensory organ. Used to study cornea plana. Human ortholog(s) of this gene implicated in arcus senilis; cornea plana; and corneal dystrophy. Orthologous to human KERA (keratocan). [provided by Alliance of Genome Resources, Apr 2022]
