Characterization and SNP identification of goat TYRP1 gene
Journal Title: Animal Science Papers and Reports - Year 2012, Vol 30, Issue 2
Abstract
As a member of tyrosinase-related family, tyrosinase-related protein-1 (TYRP1) has been reported to play an important role in melanin biosynthetic pathway in some species, but little is known about its role in goat. In this study, almost complete goat TYRP1 gene (17554 bp, HMO70243) encompassing complete CDS was identified, the coding region amounting to 1614 bp, distributed in 7 exons (2-8), and intron 5 was found to possess GC-AG as its splice sites. Dozens of SNPs as well as simple sequence repeat (SSR) motifs were detected in goat TYRP1 gene, in which 4 SSR motifs in intron 5 are combined in a tandem. Correlation analysis showed the allele A to be advantageous compared to C at site g.1263A>C and allele C compared to T at g.1428C>T , implyimg that haplotype AC is in favour of eumelanin biosynthesis, and haplotype CC is in favour of pheomelanin formation. Marked deficiency of heterozygotes occurred in Nanjiang Yellow Goat Black strain and Nanjiang Yellow Goat Fast Grow strain, indicating the high inbreeding in both strains.
