The diffusion coefficients of proteins in the cytoplasm depend on their net charge and the distribution of charge over the protein surface, with positive proteins moving up to 100-fold slower because they bind to ribosomes.
The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.
A protein modification called O-linked glycosylation regulates the interactions between vimentin molecules under normal conditions, and the ability of Chlamydia bacteria to replicate after they infect cells.
A simulation study is used to demonstrate how mistakes in identifying the experimental unit and the unit of analysis can lead to incorrect analyses and inappropriate inferences when reporting research studies.
Comparing maize to its wild ancestor teosinte advances our understanding of how it and other cereal crops evolved, and also identifies the genetic variation that can contribute to important agricultural traits.
