Sirtuin3 (SIRT3) gene molecular characterization and SNP detection in prolific and low prolific goat breeds
چکیده انگلیسی
Sirtuin3 (SIRT3) is a member of the Sirtuin family of NAD+-dependent deacetylase. They have evolved as a vital protein in preventing the activation of reactive oxygen species (ROS) in oocytes. A novel study on caprine SIRT3 was conducted, to characterize caprine SIRT3, to detect potential polymorphisms in SIRT3 and to analyze their association with litter size in the two indigenous goat breeds of India viz., the prolific Malabari and low prolific Attappady Black goats. A 1070 bp mRNA sequence of SIRT3 cDNA comprised of an ORF of 1002 bp encoding 333 amino acids, having 96% identity with bovine SIRT3. The genomic DNAs from the goats (n = 222) were subjected to PCR and single strand conformation polymorphism (SSCP) of exon 5 fragment (213 bp) of caprine SIRT3. On analysis, two genotypes viz., DD and DE were observed with frequencies of 0.63 and 0.37 respectively. Further sequencing of the PCR products of the respective genotypes revealed a novel synonymous SNP (MF176159:c.691C > T). Genotypes of this fragment had a significant influence on number of kids born (P < 0.05) with DD genotype being superior to DE genotype. These results highlight the role of SIRT3 in reproduction traits and the detected novel SNP would aid in the Marker Assisted Selection programmes and thus SIRT3 can considered as a potential candidate gene for reproduction traits in goats.
