The transcription factor-like nuclear regulator (TFNR) is a novel human gene that maps on 5q13, distal to the duplicated region that includes SMN1, the spinal muscular atrophy (SMA) determining gene. The location of TFNR allowed us to design an evolutionary model of the SMA region. The 9.5-kb TFNR transcript is highly expressed in cerebellum and weakly in all other tissues tested. TFNR encodes a protein of 2254 amino acids (aa) and contains nine repeats of a novel 55-aa motif, of yet unknown function. The coding region is organized in 32 exons. Alternative splicing of exon 15 results in a truncated protein of 796 aa. TFNR comprises a series of polypeptides that range from 55 to 250 kDa. Immunocytological studies showed that the TFNR protein is present exclusively in the nucleus, where it is concentrated in several nuclear structures. Amino acids 155-474 show significant homology to TFC5, a subunit of the yeast transcription factor TFIIIB, suggesting that TFNR is a putative transcription factor. Based on its proximity to SMN1 and its expression pattern, TFNR may be a candidate gene for atypical forms of SMA with cerebral atrophy and axonal neuropathy that have been shown to carry large deletions in the SMA region.
