ID:NR2E3_HUMAN DESCRIPTION: RecName: Full=Photoreceptor-specific nuclear receptor; AltName: Full=Nuclear receptor subfamily 2 group E member 3; AltName: Full=Retina-specific nuclear receptor; FUNCTION: Orphan nuclear receptor of retinal photoreceptor cells. Transcriptional factor that is an activator of rod development and repressor of cone development. Binds the promoter region of a number of rod- and cone-specific genes, including rhodopsin, M- and S-opsin and rod-specific phosphodiesterase beta subunit. Enhances rhodopsin expression. Represses M- and S-cone opsin expression. SUBUNIT: Interacts with PIAS3; the interaction sumoylates NR2E3 and promotes repression of cone-specific gene transcription and activation of rod-specific genes (By similarity). Component of a complex that includes NR2E3, PIAS3, NRL, CRX and/or NR1D1. Binds NR1D1. Binds direcly in the complex with CRX, PIAS3 and NR1D1 (By similarity). Interacts (via the DNA-binding domain) with CRX (via its DNA binding domain); the interaction represses S- and M-cone opsin expression. SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Eye specific; found solely in the outer nuclear layer of the adult neurosensory retina, where the nuclei of cone and rod photoreceptors reside. PTM: Di- and tri-sumoylated in developing retina. PIAS3-mediated sumoylation promotes repression of cone-specific gene expression and activation of rod-specific genes. Sumoylation on Lys-185 appears to be the main site (By similarity). DISEASE: Defects in NR2E3 are a cause of enhanced S cone syndrome (ESCS) [MIM:268100]. ESCS is an autosomal recessive retinopathy in which patients have increased sensitivity to blue light; perception of blue light is mediated by what is normally the least populous cone photoreceptor subtype, the S (short wavelength, blue) cones. ESCS is also associated with visual loss, with night blindness occurring from early in life, varying degrees of L (long, red)- and M (middle, green)-cone vision, and retinal degeneration. DISEASE: Defects in NR2E3 are the cause of retinitis pigmentosa type 37 (RP37) [MIM:611131]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP37 inheritance is autosomal dominant. SIMILARITY: Belongs to the nuclear hormone receptor family. NR2 subfamily. SIMILARITY: Contains 1 nuclear receptor DNA-binding domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
