Short summary
Intramuscular fat deposition in the longissimus dorsi muscle of Hanwoo is regulated by several genes related to lipid metabolism. One of these genes encodes the enzyme bovine glycerol-3-phosphate acyltransferase, mitochondrial (GPAM). This gene regulates triacylglycerol by gene expression. Thus, our research group has identified SNPs related to the regulation of glycerolipid synthesis in the 3′-UTR of GPAM and verified the function of SNPs affecting intramuscular fat deposition in Hanwoo.
