In a finding five years in the making, scientists have discovered a previously unknown compartment inside cellular organelles called peroxisomes. The findings have been reported in Nature ...

As a first-year graduate student in the laboratory of Bonnie Bartel, PhD, professor of biosciences at Rice University, Zachary Wright, PhD, now a postdoctoral research associate in Bartel’s lab, ...

Many proteins use targeting signals to reach the appropriate organelles. Organelle-specific receptor proteins recognize these targeting signals by direct protein-protein interactions. This is also the ...

Understanding organelle biogenesis is a central focus of cell biology. Whereas some are generated from existing organelles, others can be generated de novo. Most de novo organelle biogenesis occurs in ...
