TATA-box binding protein-associated factor 1 (TAF1), the largest subunit of the transcription factor IID complex, plays an important role in the RNA polymerase II-mediated gene transcription pathway regulating the transcription of a large number of genes related to cell division. The neuron-specific isoform of the TAF1 gene (N-TAF1) may have an essential role in neurons through transcriptional regulation of many neuron-specific genes. The present study reports the preparation and properties of a monoclonal antibody directed against N-TAF1. The monoclonal antibody, 3A-11F, specifically recognized N-TAF1 protein with no reactivity to TAF1 protein, as evidenced by immunocytochemistry and immunoprecipitation using cultured cells expressing recombinant N-TAF1 or TAF1 protein. Immunohistochemistry using 3A-11F showed that N-TAF1-imunoreactivity was detected in the nuclear region of neurons in the rat brain. The 3A-11F monoclonal antibody promises to be a useful tool for determining the expression pattern and biological function of N-TAF1 in the brain.
