The Cell Structure and Function-1 (CSF1) Study Section reviews applications that are mainly focused on protein function, processing, maturation, degradation and targeting/trafficking, as well as membrane biogenesis, function and trafficking/recycling, organelle biogenesis, inter-organelle communications and metabolism. Applications studying cell shape and motility, cellular mechanisms of cell division, cytoskeletal organization/dynamics, and intracellular transport are also reviewed here. These topics are investigated using cell biological, molecular, biochemical, and morphologic approaches and employing various model systems including but not limited to different cell types, yeast, flies, worms, frogs, plants, cultured cells, and mice.
