Genetic structure analysis of partial promoter region of Lactophorin gene in Iranian Dromedary and Bactrian camels

Camel milk is regarded as one of the richest protein sources. Lactophorin is one of the most important proteins in camel milk whey. Promoter Regions are those which have special significance in gene expression .The aim of this study was examined the structure of promoter region of Lactophorin gene with about 790 nucleotide in two Iranian Dromedary and Bactrian camels. 10 and 5 blood samples were obtained from Dromedary and Bactrian camels, respectively. The considered region was amplified and sequenced by using of specific primers. lactophorin gene structure was investigated by using genetic analysis. After aligning of the obtained gene sequences, 4 haplotype in dromedary, and 3 haplotype in Bactrian camels were observed. In addition, 12 and 10 motifs were found in dromedary and Bactrian camels, respectively. Consequently, regarding the fact that there is no information about the structure and sequencing of camel milk protein especially in Iranian species, it seems that doing some complementary studies due to specifying and analyzing the gene structure of this protein may provide more comprehensive and beneficial information about the changes and probable variations of the gene in Iranian species.
