Sequence identity (%) was determined by pairwise alignment using the DNAMAN software package (optimal alignment; gap open penalty 10.0, gap extension penalty 5.0). cDNA sequence was from the translation start ATG up till the stopcodon; the upstream regulatory region was from -1400 up till the translation start ATG. ^a: Because of a gap in upstream regulatory region of the public sequence of the rhesus monkey and hedgehog HL gene (Ensembl e!42: Dec 2006), alignments with the rhesus and hedgehog sequence were done with the sequence from -900 and -1000 up till the start ATG, respectively. ^b:the rabbit HL cDNA sequence was taken from [38].
