Reelin 是一种细胞外蛋白,通过激活两种受体(极低密度脂蛋白受体 (VLDLR) 和载脂蛋白 E 受体 2 (ApoER2))以及 Disabled-1 (Dab1) 的磷酸化来指导大脑皮质结构的组织。 Lis1 是 Pafah1b1 基因的产物,是脑血小板激活因子乙酰水解酶 1b (Pafah1b) 复合物的组成部分,并响应 Reelin 与磷酸化的 Dab1 结合。在这里,我们研究了整个 Pafah1b 复合物在 Reelin 信号传导和皮质层形成中的参与,发现 Pafah1b 复合物的催化亚基 Pafah1b2 和 Pafah1b3 特异性结合 VLDLR 的 NPxYL 序列,但不结合 ApoER2。复合Pafah1b1+/-;Apoer2−/−突变小鼠在前脑中表现出类似卷轴的表型,包括皮质层倒置和海马解体,而双Pafah1b1+/-;Vldlr−/−突变小鼠则不然。这些结果表明 Pafah1b 复合体和 Reelin 之间的串扰发生在 VLDLR 受体下游。
Reelin is an extracellular protein that directs the organization of cortical structures of the brain through the activation of two receptors, the very low-density lipoprotein receptor (VLDLR) and the apolipoprotein E receptor 2 (ApoER2), and the phosphorylation of Disabled-1 (Dab1). Lis1, the product of the Pafah1b1 gene, is a component of the brain platelet-activating factor acetylhydrolase 1b (Pafah1b) complex, and binds to phosphorylated Dab1 in response to Reelin. Here we investigated the involvement of the whole Pafah1b complex in Reelin signaling and cortical layer formation and found that catalytic subunits of the Pafah1b complex, Pafah1b2 and Pafah1b3, specifically bind to the NPxYL sequence of VLDLR, but not to ApoER2. Compound Pafah1b1+/−;Apoer2−/− mutant mice exhibit a reeler-like phenotype in the forebrain consisting of the inversion of cortical layers and hippocampal disorganization, whereas double Pafah1b1+/−;Vldlr−/− mutants do not. These results suggest that a cross-talk between the Pafah1b complex and Reelin occurs downstream of the VLDLR receptor.
