Abstract:
Peter Satir has devoted his research career to elucidating the structural basis for ciliary motility. His ingenious use of structural analysis, combined with identification of powerful model systems, provided a model for the sliding microtubule hypothesis of ciliary bending and led to the discovery that dynein is a 'minus-end'-directed motor whose regulated activity underpins the bending motion of cilia. Here, we focus on ciliary motility to illustrate Satir's pioneering contributions to cell biology.

Structural Protein Function
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to form...
Synteny and Evolution
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...
Animal and Plant Cell Structure
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during cell...
