TATA-box binding protein associated factor 1 (TAF1) protein is the largest and the essential component of the TFIID complex in the pathway of RNA polymerase II-mediated gene transcription, and it regulates transcription of a large number of genes related to cell division. The neuron-specific isoform of the TAF1 gene (N- TAF1), which we reported previously, may have an essential role in neurons through transcriptional regulation of many neuron-specific genes. In the present study, we cloned the full-length cDNA that encodes the mouse homologue of N-TAF1 (N-Taf1) protein. By carrying out of real time RT-PCR, we investigated the expression analysis of the N- Taf1 mRNA in mouse tissues and cell lines. As well as the human N- TAF1, the N- Taf1 showed limited expression in the brain and neuroblastoma, whereas Taf1 expressed elsewhere. Furthermore, in mouse embryo head or mouse brain, mRNA expression of TAF1 changes dramatically during development but N- Taf1 showed sustained expression. Our result suggests that the N- Taf1 gene has an important role in non-dividing neuronal cell rather than in cell division and proliferation during neurogenesis.
