Endocytic membrane trafficking in the control of centrosome function

Research output: Contribution to journalReview article

Abstract

Until recently, endocytic trafficking and its regulators were thought to function almost exclusively on membrane-bound organelles and/or vesicles containing a lipid bilayer. Recent studies have demonstrated that endocytic regulatory proteins play much wider roles in trafficking regulation and influence a variety of nonendocytic pathways, including trafficking to/from mitochondria and peroxisomes. Moreover, new studies also suggest that endocytic regulators also control trafficking to and from cellular organelles that lack membranes, such as the centrosome. Although endocytic membrane trafficking (EMT) clearly impacts pathways downstream of the centrosome, such as ciliogenesis (including transport to and from cilia), mitotic spindle formation, and cytokinesis, relatively few studies have focused on the growing role for EMT more directly on centrosome biogenesis, maintenance and control throughout cell cycle, and centrosome duplication. Indeed, a growing number of endocytic regulatory proteins have been implicated in centrosome regulation, including various Rab proteins (among them Rab11) and the leucine-rich repeat kinase 2. In this review, we will examine the relationship between centrosomes and EMT, focusing primarily on how EMT directly influences the centrosome.
