Cell Mol Life Sci. 2020 Jan;77(2):275-287. doi: 10.1007/s00018-019-03270-7. Epub 2019 Aug 17.

Abstract

Plasma membranes are heterogeneous and laterally compartmentalized into distinct microdomains. These membrane microdomains consist of special lipids and proteins and are thought to act as signaling platforms. In plants, membrane microdomains have been detected by super-resolution microscopy, and there is evidence that they play roles in several biological processes. Here, we review current knowledge about the lipid and protein components of membrane microdomains. Furthermore, we summarize the dynamics of membrane microdomains in response to different stimuli. We also explore the biological functions associated with membrane microdomains as signal integration hubs. Finally, we outline challenges and questions for further studies.

Keywords: Assembly; Lipid; Microdomain marker proteins; Motion; Stress.
