TIPs (tonoplast intrinsic proteins) have been traditionally used as markers for vacuolar identity in a variety of plant species and tissues. In the present article, we review recent attempts to compile a detailed map of TIP expression in Arabidopsis, in order to understand vacuolar identity and distribution in this model species. We discuss the general applicability of these findings. We also review the issue of the intracellular targeting of TIPs and propose key emerging questions relative to the cell biology of this protein family.
液泡膜内在蛋白（TIPs）传统上被用作多种植物物种和组织中液泡特性的标记物。在本文中，我们回顾了最近尝试在拟南芥中绘制 TIP 表达详细图谱的努力，以了解该模式物种中液泡的特性和分布。我们讨论了这些发现的普遍适用性。我们还回顾了 TIP 细胞内靶向的问题，并提出了与该蛋白家族的细胞生物学相关的关键新问题。
