Nucleotide sequence of the putative promoter located in intron 3. The darkly shaded region indicates exon 4, lightly shaded arrows the twoAlu repeats. Potential binding sites for transcription factors are boxed. The predicted transcription start site is marked by a bold arrow; the ATM start codon by a hatched arrow. Numbers along the right side of the figure indicate the nucleotide numbering of the database entry (accession no. U82828).
