Predicted amino acid sequences. (a) NABC1. (b) ZNF217. Eight putative C2H2 zinc finger domains are indicated in bold. A repeated motif in exon 1 is double underlined. Lines above the text indicate the positions of two putative tyrosine phosphorylation sites predicted by the PROSITE pattern search algorithm. A putative proline-rich transcription activation domain is encoded by amino acids 757-1005 and is composed of 16% proline. Exon boundaries were determined from the cDNA and genomic sequences and are marked with arrows. Exon 1 codes for 455 aa and exon 3 codes for 517 aa. The amino acid sequence of the alternately processed exon 4 is underlined.
