一般描述
重组人胰岛素(rHu)在功能和结构上与天然人序列相同。由两个多肽链组成的激素,rHu 胰岛素的 A 链(21 个氨基酸)和 B 链(30 个氨基酸)通过半胱氨酸残基之间的二硫键共价连接。这种经基因工程改造的人胰岛素是全序列分子,通过重组 DNA 技术在面包酵母中生产。
应用
无血清培养基补充剂(如胰岛素)对于常用哺乳动物细胞系的长期生长至关重要。当培养基中缺少胰岛素时,细胞形态和生长速度可能会受到干扰。
- 重组人胰岛素已用在培养基中的间充质干细胞的成脂诱导。
- 它已被用作气道上皮细胞的细胞培养基中的补充剂。
- 它已用于细胞分化、GLUT4(4 型葡萄糖转运蛋白)易位测定的培养基中,并通过表面等离振子共振研究胰岛素与胰岛素受体的相互作用。
生化/生理作用
由胰岛β-细胞所产生的二链多肽激素。其分子量为~5800 Da。α链和β链是由两个链间二硫键所连接的。α链含有一个链间二硫键。胰岛素可调节细胞对葡萄糖、氨基酸和脂肪酸的摄取、利用和储存,并抑制糖原、蛋白质和脂肪的分解。
