Sequence of the

ABC7 promoter and first exon. Putative transcription factor-binding sites are boxed with the factor identified above and a caret indicating the orientation. The 5′ ends of cDNA and EST sequences from GenBank are indicated by letters a to j, where a = AF038950; b = AF133659; c = AA226777; d = AF078777 andAA305099; e = AI34738; f = AI241249, AA971 952, AA282065,AA810484, AA810091, AA923765, and AI873369; g = AA815080; h = AI016955; i = AA766839; and j = AA732107. 5′-RACE products are indicated by 1 or 2, indicating the number of RACE ends found at each position. The first exon/intron boundary is indicated by a vertical line flanked with the exon numbers. This sequence has been deposited in GenBank with the accession number GB:AF241872.
