cDNA sequence and genomic structute of d4h-like a) Nucleotide sequence of d4h-like cDNA and the predicted amino acid residues. The open reading frame was underlined. Corresponding amino acid residues were above the nucleotide sequence. Putative polyadenylation signal was in box and the polyA tail was highlighted with shadow. b) Genomic organization of d4h- like and d4h.
