Prkag3基因编码的是AMP-activated protein kinase(AMPK)的γ3亚基,AMPK是一种异源三聚体酶,负责控制细胞能量稳态,以响应环境或营养压力。PRKAG3基因的变异与猪的肉品质性状相关。在羊的PRKAG3基因中,发现了两个变异序列,分别位于外显子3区域和4-6区域,这些变异可能影响AMPK的活性,进而影响羊肉品质性状[1]。在猪中,PRKAG3基因的表达与肌肉的糖酵解潜能和肌内脂肪含量相关,PRKAG3基因启动子区域的SNP变异与肉品质性状相关[2]。在人类骨骼肌中,PRKAG3的表达与肌肉的体积和线粒体功能相关[3]。在牛的PRKAG3基因中,发现了32个SNP,其中有5个改变了PRKAG3蛋白序列中的氨基酸[4]。在意大利大白猪中,PRKAG3基因的SNP变异与肉品质性状相关[5]。在马的PRKAG3基因中,发现了7个SNP,其中5个引起了氨基酸替换[6]。在猪的PRKAG3基因中,发现了4个错义替换,这些替换可能影响肉品质[7]。通过比较人和猪的PRKAG3基因序列,发现了保守的重复序列和潜在的新外显子[8]。在斯洛文尼亚干腌火腿中,PRKAG3和CAST基因的SNP变异与火腿的品质性状相关[9]。在牛的PRKAG3基因中,发现了7个SNP,这些SNP可能影响肌肉相关的遗传疾病或肉品质性状[10]。

综上所述,Prkag3基因的变异与多种动物的肉品质性状相关,这表明PRKAG3基因在调节动物能量代谢和肉品质方面起着重要作用。未来的研究可以进一步探索PRKAG3基因变异对动物肉品质的影响机制,以及如何利用这些变异来改善动物肉品质。
