一般描述

牛乳脂蛋白脂酶(LPL)是一种糖蛋白。它以同型二聚体形式存在,由两个N-连接的寡糖组成。具有热不稳定性。

应用

牛乳脂蛋白脂酶已用于:
  • 研究脂蛋白脂酶作为补充剂对乳腺癌细胞MDA-MB-231中DiI(1,1′-双十八烷基-3,3,3′-四甲基吲哚碳菁高氯酸盐)-极低密度脂蛋白(VLDL)摄取的影响
  • 处理人脑微血管内皮细胞(HBMEC)以脂解富含三酰甘油的脂蛋白(TGRL)
  • 检测脂蛋白脂酶对正常人星形胶质细胞基因表达的影响

生化/生理作用

牛乳脂蛋白脂酶(LPL)具有最高的脂解活性。它与酪蛋白胶束有关。LPL调节甘油三酯利用度,具有位点特异性。脂酶通常催化甘油三酯的脂裂解,尤其是甘油三酯sn-1和sn-3位的脂肪酸。

单位定义

p -硝基苯丁酸酯为底物,在 37°C、pH 7.2 条件下,1 个单位每分钟将释放 1.0 nmol p -硝基苯酚。

外形

用 3.8 M 硫酸铵、0.02 MTris HCl (pH 8.0) 混悬

Apolipoprotein F (ApoF) modulates lipoprotein metabolism by selectively inhibiting cholesteryl ester transfer protein activity on LDL. This ApoF activity requires that it is bound to LDL. How hyperlipidemia alters total plasma ApoF and its binding to LDL are poorly understood.

The apolipoprotein E2 (Lys146-->Gln) variant is associated with a dominant form of familial dysbetalipoproteinemia. Heterozygous carriers of this variant have elevated levels of plasma triglycerides, cholesterol, and apolipoprotein E (apoE). It was hypothesized that the high amounts of triglycerides in
