Reticulons (RTNs) are membrane-spanning proteins sharing a typical domain named reticulon homology domain (RHD). RTN genes have been identified in all eukaryotic organisms examined so far, and the corresponding proteins have been found predominantly associated to the endoplasmic reticulum membranes. In animal and yeast, in which knowledge of the protein family is more advanced, RTNs are involved in numerous cellular processes such as apoptosis, cell division and intracellular trafficking. Up to now, a little attention has been paid to their plant counterparts, i.e., RTNLBs. In this review, we summarize the data available for RTNLB proteins and, using the data obtained with animal and yeast models, several functions for RTNLBs in plant cells are proposed and discussed.
