Characterization of Exon 3 of PROP1 gene and screening of H173R polymorphism in Karan Fries bulls

Present study was done in thirty Karan Fries bulls to characterize the Exon 3 of PROP1 gene and to screen for the H173R polymorphism as well as other variations including reported and novel SNPs in the targeted region. The exon 3 was characterized by sequencing the amplicons obtained after PCR amplification using custom designed primers. The BLAST analysis of the obtained sequence yielded 100% and 99% homology with sequences of Bos taurus and bison respectively. The multiple alignment of the target region sequence with Bos taurus reference sequence revealed that the bulls under the study were free of H173R mutations. No variations were observed thus giving the targeted region a highly conserved one.
