Organelle structure and biogenesis
What controls the dynamics of the transitional ER? Secretory proteins exit from the endoplasmic reticulum (ER) at specialized transitional ER (tER) sites. Benjamin Glick (University of Chicago) described the role of Sec16 in regulating tER organization in the yeast Pichia pastoris. Membrane-associated Sec16 seems to slow ER export. A mutation that redistributes Sec16 to the cytosol relieves thi...
متن کاملOrganelle biogenesis and autophagy
Is mitochondrial volume maintained during polarized cell growth? How well do cells ensure that they maintain uniform organelle distribution when they undergo polarized cell growth and subsequent division. S. Rafelski from the Marshall laboratory at University of California–San Francisco used three-dimensional, computationalmodeling methods to demonstrate that mitochondrial volume is maintained ...

Using representative examples primarily from the yeast Saccharomyces cere-One hallmark of eukaryotic cells is that they contain visiae, we highlight in this review some recent insights many functionally ...
متن کاملOrganelle biogenesis and interorganellar connections
Membrane contact sites (MCSs) allow the exchange of molecules and information between organelles, even when their membranes cannot fuse directly. In recent years, a number of functions have been attributed to these contacts, highlighting their critical role in cell homeostasis. Although inter-organellar connections typically involve the endoplasmic reticulum (ER), we recently reported the prese...
