title: Sharing with your children: Mechanisms of peroxisome inheritance.
abstract: Organelle inheritance is the process by which eukaryotic cells actively replicate and equitably partition their organelles between mother cell and daughter cell at cytokinesis to maintain the benefits of subcellular compartmentalization. The budding yeast Saccharomyces cerevisiae has proven invaluable in helping to define the factors involved in the inheritance of different organelles and in understanding how these factors act and interact to maintain balance in the organelle populations of actively dividing cells. Inheritance factors can be classified as motors that transport organelles, tethers that retain organelles, and connectors (receptors) that mediate the attachment of organelles to motors and anchors. This article will review how peroxisomes are inherited by cells, with a focus on budding yeast, and will discuss common themes and mechanisms of action that underlie the inheritance of all membrane-enclosed organelles.
