Rapid diffusion-state switching underlies stable cytoplasmic gradients in the Caenorhabditis elegans zygote [Developmental Biology]

Protein concentration gradients organize cells and tissues and commonly form through diffusion away from a local source of protein. Interestingly, during the asymmetric division of the Caenorhabditis elegans zygote, the RNA-binding proteins MEX-5 and PIE-1 form opposing concentration gradients in the absence of a local source. In this study, we...
