    text
  • coexpressed with CRX by photoreceptors
  • localized to the cell bodies of mature rods and cones
  • basic FUNCTION
  • photoreceptor cell-specific nuclear receptor, involved in determining photoreceptor phenotype during retinogenesis
  • involved in regulating and maintaining the expression of rod photoreceptor-specific genes and may be in transcriptional regulatory network(s) during rod differentiation
  • dual-function transcriptional regulator acting in concert with CRX to promote and maintain the function of rod photoreceptors
  • functioning either directly or indirectly, as a repressor of cone-specific genes in rod photoreceptor cells
  • playing a critical role in establishing functional specificity of neural retina leucine zipper expressing photoreceptor precursors during retinal neurogenesis
  • acting as a negative regulator for cell proliferation of retina neurons
  • playing a key role in the regulation of photoreceptor-specific genes during rod development and maintenance
  • a pivotal role in the differentiation of photoreceptors
  • in postmitotic rods, influences rod cell differentiation, whereas, in late mitotic progenitors, its primary function is to suppress the cone-generation program
  • acting simultaneously in different cell types: in late mitotic progenitors, newly differentiating post mitotic cells, and mature rods and cones
  • photoreceptor-specific nuclear receptor believed to play a role in photoreceptor development, differentiation, and survival
  • dual role in specification of photoreceptor fate during development as well as photoreceptor maintenance in the adult
  • influence the competency of retinal progenitors while simultaneously directing the rod and cone differentiation
  • represses cone-specific genes and activates several rod-specific genes
  • a potential role for NR1D1, in conjunction with its cofactor NR2E3, in regulating transcriptional networks critical for photoreceptor development and function
  • CELLULAR PROCESS nucleotide, transcription

    small molecule
    protein
  • nuclear receptor subfamily 1, group D, member 1, NR1D1 and neural retina leucine zipper, NRL
  • cone-rod homeobox, CRX
  • PNR co-repressor Ret-CoR
  • NRL and NR2E3 have overlapping functions, and NRL binds to a sequence element in the NR2E3 promoter and enhances its activity synergistically with the homeodomain protein CRX
