Amino acid sequence based on Cytochrome b gene in Kejobong goat and its genetic relationships among several local goats in Asia.

Aim: This study aimed to analyze the amino acid sequence of Cytochrome b ( Cyt b ) gene in Kejobong goat and its genetic relationships with local goats located in Asia.

Materials and Methods: A total of 28 heads of Kejobong goat were purposively sampled. The deoxyribonucleic acid (DNA) was extracted from blood using gSYNC DNA mini kit (Geneaid Biotech Ltd.). Cyt b gene was amplified using polymerase chain reaction (PCR) method with CytbCapF and CytbCapR primers. The amplified PCR products were sequenced for further analysis.

Results: There were a total 377 amino acid sequences translated from 1140 base pair (bp) of Cyt b gene, 99.20% of it were monomorphic, amino acid alterations were found at site 16th , 121st , and 231st , and Kejobong goat was in the same cluster with Southeast Asian local goats.

Conclusion: Most of the amino acid sequence on Cyt b gene in Kejobong goat is monomorphic (99.20%), only a few nucleotide mutations were found that causing amino acid alteration in three sites (0.80%). Kejobong goat has a close genetic relationship to several local goats in Southeast Asian.
