Mitochondria can trigger massive endocytosis by releasing coenzyme A into the cytoplasm and thereby promoting the addition of fatty acids to surface membrane proteins.
Reoxygenation of anoxic cardiac tissue promotes massive endocytosis that is triggered by release of coenzymeA from mitochondria, followed by palmitoylation of membrane proteins, sarcolemma vesiculation, and transfer of sarolemma vesicles to large endosomes and vacuoles.
High-resolution optical microscopy is used to reveal the organization of extracellular matrix proteins within the basement membrane of the blood filtration barrier in the kidney at the nanometer scale.

Evidence that certain proteins can be transported between Golgi via structures that resemble COPI vesicles suggests that these vesicles could also be involved in the transport of proteins from the cis to the trans face of the Golgi.
During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.
