Photoreceptor-specific nuclear receptor (NR2E3)

Orphan nuclear receptor of retinal photoreceptor cells. Transcriptional factor that is an activator of pole development and repressor of cone development.

Binds the promoter region of a number of pole - and cone-specific genes, including rhodopsin, M- and S-opsin and rod-specific phosphodiesterase beta subunit. Enhances rhodopsin expression.
