Glucose-stimulated insulin secretion involves G protein (Rac1)-mediated cytoskeletal remodeling and vesicular transport and fusion with the plasma membrane. Recent evidence implicates at least three guanine nucleotide exchange factors (GEFs), namely, Tiam1, Vav2, and P-Rex1, in glucose-induced activation of Rac1 and insulin secretion. This Viewpoint highlights potential mechanisms underlying Tiam1/Vav2/P-Rex1 sensitive Rac1-mediated insulin secretion in the glucose-stimulated β-cell.

多种鸟嘌呤核苷酸交换因子介导葡萄糖诱导的 Rac1 激活和胰岛素分泌:是精确的调节控制还是来自同一个豆荚的两颗豌豆的情况?

葡萄糖刺激的胰岛素分泌涉及 G 蛋白 (Rac1) 介导的细胞骨架重塑以及囊泡运输以及与质膜的融合。最近的证据表明至少三种鸟嘌呤核苷酸交换因子 (GEF),即 Tiam1、Vav2 和 P-Rex1,参与葡萄糖诱导的 Rac1 激活和胰岛素分泌。该观点强调了葡萄糖刺激的 β 细胞中 Tiam1/Vav2/P-Rex1 敏感的 Rac1 介导的胰岛素分泌的潜在机制。
