Abstract

The differentiation of placental cytotrophoblasts (CTBs) into the syncytiotrophoblast (STB) layer results in a significant remodeling of the plasma membrane proteome. Here, we use a peroxidase-catalyzed proximity labeling strategy to map the dynamic plasma membrane proteomes of CTBs and STBs. Coupled with mass-spectrometry-based proteomics, we identify hundreds of plasma membrane proteins and observe relative changes in protein abundance throughout differentiation, including the upregulation of the plasma-membrane-localized nonreceptor tyrosine kinase LYN. We show that both siRNA-mediated knockdown and small molecule inhibition of LYN kinase function impairs CTB fusion and reduces the expression of syncytialization markers, presenting a function for LYN outside of its canonical role in immunological signaling. Our results demonstrate the use of the proximity labeling platform to discover functional regulators within the plasma membrane and provide new avenues to regulate trophoblast differentiation.

摘要

胎盘细胞滋养层(CTBs)向合体滋养层(STB)的分化导致质膜蛋白质组发生显著重塑。在这里,我们使用过氧化物酶催化的邻近标记策略来绘制 CTB 和 STB 的动态质膜蛋白质组图谱。结合基于质谱的蛋白质组学,我们鉴定了数百种质膜蛋白,并观察到整个分化过程中蛋白质丰度的相对变化,包括质膜定位的非受体酪氨酸激酶 LYN 的上调。我们表明,siRNA 介导的 LYN 激酶功能敲低和小分子抑制都损害了 CTB 融合并降低了合胞体标记物的表达,表明 LYN 在其免疫信号传导的典型作用之外具有功能。我们的结果证明了使用邻近标记平台在质膜内发现功能调节剂的用途,并为调节滋养层分化提供了新的途径。
