Abstract: According to MTNR1a cDNA sequence of sheep(gi:15U14109), human(gi:U14108), cattle(gi:U73327), mice(gi:U52222) and other species announced in GenBank,primers were designed. The 275 bp fragment of exon 1 of MTNR1a gene was amplified by PCR in Inner Mongolian Cashmere goat. The PCR products were cloned and sequenced. By compared with database of GenBank, it turned out that homology of nucleotide sequence of exon 1 MTNR1a gene in Cashmere goat with sheep, cow were 99% and 96%, respectively. It showed that the sequence was MTNR1a gene exon 1 sequence in Cashmere goat. Using DNAStar software to analysis, 257 nucleotides of the gene sequence was gotten.The sequence contained 5'UTR 23 nucleotides, translation initiation codon ATG and the N terminal 78 amino acid coding sequences.
