Background: Heat shock proteins (HSPs) play important roles in the responses to different environmental stresses. In this study, the genomic and proteomic characteristics of three HSPs (HSP70, HSP90-α and HSP90-β) in five even-toed ungulates (sheep, goats, water buffalo, Zebu cattle and cattle) were analyzed using Multiple sequence alignment, SWISS modeling and phylogenetics analysis tools. Results: The bioinformatic analysis revealed that the HSP70 gene in cattle, Zebu cattle, and goat is located on chromosome 23, and is intronless, while in water buffalo and sheep it is located on chromosomes 2 and 20, respectively, and contains two exons linked by one intron. The HSP90-α gene is located on chromosome 21 in cattle, Zebu cattle, and goat, while in water buffalo and sheep it is located on chromosomes 20 and 18, respectively. The HSP90-β gene is located on the same chromosome as the HSP70 gene and contains 12 exons interspersed by 11 introns in all studied animals. In silico Expasy translate tool analysis revealed that HSP70, HSP90-α and HSP90-β encode 641, 733, and 724 amino acids, respectively. The data revealed that goat HSP70 protein has seven variable amino acid residues, while in both sheep and cattle only one such amino acid was detected. Conclusions: This study will be supportive in providing new insights into HSPs for adaptive machinery in these studied animals and selection of target genes for molecular adaptation of livestock.How to cite: Raza SHA, Hassanin AA, Dhshan AIM, et al.
