(A) Genomic DNA and cDNA structure of Dfy and deduced amino acid sequence of mouse Duffy-like protein. Amino acid residues are numbered on left; nucleotide positions are numbered onright. The exon and intron sequences are shown in uppercase and lowercase, respectively. The consensus sequence at the intron splice site is indicated in boldface letters. The three potential carbohydrate-binding sites to asparagine residues are shown in up arrows. The primers’ nucleotide sequences are shown in lowercase, italic, and boldface letters. P2 nucleotides are shown by a solid line and P1 by a dotted line. The underline is the polyadenylation signal. (▴) The polyadenylation site; (♦) the stop codon. (B) 5′-end promoter flanking sequence of Dfy. (▿) The position (+1) of the major transcription initiation site. Consensus sequences for the transcription factor binding sites are boxed, and the name of the corresponding factors are shown. The arrows indicate consensus sequences in sense strand (right) and antisense strand (left).
