General description
来自胎牛血清的胎球蛋白是一种血浆糖蛋白。它是一种64 kDa的糖蛋白,由肝脏和脂肪组织产生。
在胚胎癌细胞培养中,以500 mg/ml的浓度,将来自胎牛血清并用作胎球蛋白的一种糖蛋白(与胰岛素、转铁蛋白和2-巯基乙醇一同)添加到无血清的F12培养基中。

Application
胎牛血清中的胎球蛋白已用于:
- 作为测定神经氨酸酶活性的底物
- 验证唾液酸酶的特异性
- 稳定m-钙蛋白酶
Biochem/physiol Actions
胎球蛋白可作为胰岛素受体酪氨酸激酶的抑制剂。它可调节骨骼重塑和钙的代谢。胎球蛋白可调节血管钙化、胰岛素抵抗、蛋白酶活性控制、角质形成细胞迁移和乳腺肿瘤细胞增殖信号。它可作为神经退行性疾病的一种生物标志物。胎球蛋白具有抗炎症属性。
