Transcriptional regulator that plays a role in retinal development and maintenance. Binds DNA. Can associate with the proximal promoter regions of PAX6 and SP4, and their known targets including ARR3, RHO, OPN1MW2 and OPN1SW. Widely expressed. In the eye, expression is greatest in the retina and least in the lens and cornea. Belongs to the krueppel C2H2-type zinc-finger protein family. Truncated N-terminus. Probable cloning artifact.
