The abundance and size of cellular organelles vary depending on the cell type and metabolic needs. Peroxisomes constitute a class of cellular organelles renowned for their ability to adapt to cellular and environmental conditions. Together with transcriptional regulators, two groups of peroxisomal proteins have a pronounced influence on peroxisome size and abundance. Pex11-type peroxisome proliferators are involved in the proliferation of peroxisomes, defined here as an increase in size and/or number of peroxisomes. Dynamin-related proteins have recently been suggested to be required for the scission of peroxisomal membranes. This review surveys the function of Pex11-type peroxisome proliferators and dynamin-related proteins in peroxisomal proliferation and division.
