Photoreceptor cell-specific nuclear receptor

The photoreceptor cell-specific nuclear receptor (PNR), also known as NR2E3 (nuclear receptor subfamily 2, group E, member 3), is a protein that in humans is encoded by the NR2E3 gene.[1] PNR is a member of the nuclear receptor super family of intracellular transcription factors.

Function

PNR is exclusively expressed in the retina. The main target genes of PNR are rhodopsin and several opsins which are essential for sight.[2]

Clinical significance

Mutations in the NR2E3 gene have been linked to several inherited retinal diseases, including enhanced S-cone syndrome (ESCS),[3] a form of retinitis pigmentosa,[4] and Goldmann-Favre syndrome.[5]
