Anti-NRL (Neural Retina Leucine Zipper) from rabbit

Neural retina-specific leucine zipper protein (UniProt: P54846; also known as NRL) is encoded by the Nrl gene (Gene ID: 18185) in murine species. NRL is a bZIP transcription factor of the MAF family that regulates the expression of several rod-specific genes, including RHO and phosphodiesterase 6B. NRL is reported to be present in the nuclei of developing and mature rods but not cones. It interacts with the homeodomain protein CRX and synergistically regulates rhodopsin expression. It is also reported to interact with FIZ1 and this interaction can repress transactivation. It consists of a minimal transactivation domain (aa 30-93), a basic motif (aa 159-185), and a leucine-zipper (aa 187-208). The minimal transactivation domain (MTD) is conserved across the MAF family and it may activate transcription by recruiting TBP and associated factors at the promoters of target genes. In developing mouse retina, Nrl expression is reported to precede the appearance of known markers for differentiated rods. The transcriptional activity of NRL is modulated by sumoylation on RHO and NR2E3 promoters. (Ref.: Prabodha, K et al. (2001). J. Biol. Chem 276 (39): 36824-30).
