| abstractText | Here we describe the cloning and expression pattern of a new bHLH-PAS domain gene, Npas3. Npas3 shares 50.2% amino acid sequence identity with Npas1 and a lesser similarity with other members of the bHLH-PAS domain family of transcription factors. Northern blot analysis detected Npas3 mRNA between 11.5 and 17.5 d.p.c. in embryonic development and exclusively in the adult brain. Whole-mount and section in situ hybridization assays revealed expression of Npas3 between 9.5 and 11.5 d.p.c. in the developing neural tube. In addition, Npas3 mRNA was expressed throughout the neuroepithelium of the developing central nervous system between 10. 5 and 12.5 d.p.c. Interestingly, at 14.5 d.p.c., the expression of Npas3 mRNA became restricted to the neopallial layer of the cortex. At 12.5 d.p.c., Npas3 mRNA was evident in nonneural tissues such as the developing dermis and mesenchyme surrounding the otic and nasal placodes. Expression was also detected in the developing cardiac valves, limb and developing kidney. |
