The rat bfp/znf179 transcript for a member of the RING finger protein family, is expressed in brain and up-regulated in neural differentiation of P19 embryonic carcinoma cells. Here we report the full-length cDNA structure of human BFP/ZNF179 and its expression profile. The cDNA clone consists of 3082 nucleotides and encodes an open reading frame of a 632-amino acid protein that contains a RING finger domain at its N-terminus, and alanine-rich and glycine-rich domains at its C-terminus. Reverse transcriptase polymerase chain reaction analysis of various human tissues indicated that BFP/ZNF179 is predominantly expressed in brain.
