阿拉伯半乳聚糖蛋白和细胞壁相关激酶（WAK）被怀疑是细胞质和细胞壁界面的调节参与者。WAK(s)和阿拉伯半乳聚糖都显示可能代表阿拉伯半乳聚糖蛋白(s)，在计算光学切片显微镜下可见。阿拉伯半乳聚糖以多面体排列在细胞膜的外表面。WAK和其他尚未确定的蛋白质似乎在阵列的顶点将膜固定在细胞壁上。有证据表明，该阵列承担了膜所经历的机械应力的重要组成部分，并且推测阿拉伯半乳聚糖蛋白、WAK和阵列的其他组分的结构组织对内膜活动、生长和分化的协调至关重要。这个阵列被命名为浆母网。
Arabinogalactan protein and wall-associated kinase (WAK) are suspected to be regulatory players at the interface between cytoplasm and cell wall. Both WAK(s) and arabinogalactan shown likely to represent arabinogalactan protein(s) have been visualized there with computational optical-sectioning microscopy. The arabinogalactan occurs in a polyhedral array at the external face of the cell membrane. WAK, and other proteins as yet unidentified, appear to fasten the membrane to the wall at vertices of the array. Evidence is presented that the array bears an important part of the mechanical stress experienced by the membrane, and it is speculated that the architectural organization of arabinogalactan protein, WAK, and other components of the array is critical for coordination of endomembrane activities, growth, and differentiation. The array has been named the plasmalemmal reticulum.
