beta-lactoglobulin

Beta-lactoglobulin is a major whey protein in ruminant milk. Cis-acting elements(β lg core promoter, LCR and MAR) and trans-acting factors ( transcription factors and hormones) affect the expression of β lg.

β乳球蛋白（BLG）是反刍动物乳汁中的主要乳清蛋白，BLG表达受到βlg核心启动子、LCR、MAR等顺式作用元件和激素、转录因子等反式作用因子的调控。

For beta-lactoglobulin, a cow's milk allergen that is resistant to pepsin cleavage, bile acids enhanced its proteolysis by pancreatic proteases even after incubation under gastric conditions.

如beta-乳球蛋白是牛乳中的一种抗原蛋白，不易被胃蛋白酶分解，即使在胃内环境中胆汁酸也可以增强胰蛋白酶对它的分解作用。

Beta-lactoglobulin ( BLG) is a major protein in the milk ( 56-60% of total cow whey proteins) and is considered to be a dominant allergen.

p-乳球蛋白（BLG）是牛奶中的主要蛋白，要占到乳清蛋白总量的一半以上，被认为是导致乳过敏症的过敏原。
