Lipids and proteins are not evenly distributed within the plasma membrane ( PM ), but instead segregate laterally into many specialized microdomains whose functional relevance is not clear. In this issue, Busto et al ([Busto JV, 2018]) demonstrate that substrate flux through a nutrient transporter drives the lateral relocation of the transporter between specific microdomains at the yeast PM , suggesting that regulating the lateral plasma membrane compartmentalization for individual proteins could be a general process for cellular response to environmental conditions.
