一般描述
INS基因会编码胰岛素原前体，其可被酶促转化为胰岛素。胰岛素是在产胰岛素胰岛β细胞中生成的。前胰岛素原是在内质网中被转化为胰岛素原的，并随后通过蛋白水解在新形成的胰岛素分泌颗粒中形成胰岛素。胰岛素的产生受到INS启动子近端区域内∼400 bp之内特定DNA元件的严格调控。
应用
人胰岛素已用于以下应用：
- 成脂分化测定（在制备培养基补充剂中）
- 孵育用于评估胰岛素作用的细胞
- 质谱（用于外部校准）
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。
胰岛素负责两种类型的作用- 兴奋性和抑制性。在其兴奋作用中，它可增加葡萄糖和脂质合成的摄取，而在其抑制作用中它可抑制糖原分解、糖异生、脂解、蛋白水解和生酮作用。胰岛素分泌异常会导致各种疾病，如糖尿病、高血糖症或低血糖症。I型糖尿病是胰腺β细胞自身免疫破坏的结果，可导致胰岛素耗竭。突变体INS基因诱导的青年糖尿病（MIDY）综合征是一种由错义突变引起的常染色体显性遗传疾病，可导致异常的胰岛素原折叠。葡萄糖耐量降低（IGT）或非胰岛素依赖型糖尿病（NIDDM）是由对胰岛素刺激的葡萄糖摄取的抵抗而引起的。
