| Summary: | The current research explored the link between genetic diversity in the Mitogen-activated
protein kinase 15 (MAPK 15) gene of buffalo and the traits related to milk composition and production,
employing PCR-SSCP and Sanger sequencing techniques. The MAPK 15 gene, situated on bovine
chromosome 14 and encompassing 1,892 base pairs, consists of 14 exons and encodes the enzyme Mitogenactivated protein kinase 15 (566 amino acids). This enzyme plays an essential role in the development of
the mammary glands and the lactation process. It engages in intracellular signalling pathways that oversee
various cellular functions, including growth and differentiation, suggesting its potential impact on milk
production and the properties of milk composition. The modified high-salt approach was used to extract
genomic DNA from blood samples taken from 100 Murrah buffaloes. PCR amplified products were
resolved by 8% non-denaturing PAGE. Resolved PCR products were genotyped according to the band
pattern during SSCP. The examination uncovered a uniform pattern during PCR-SSCP, hinting at a likely
lack of variation, which implies a significant level of preservation in Murrah buffaloes. The uniform
structure of the MAPK15 gene in this research can assist in distinguishing the Murrah breed from various
other buffalo breeds. The candidate gene needs further validation in a larger cohort for use in the selection
of buffalo cows with required milk composition traits. |
