Toll-like receptor 9 (TLR9) is localized in the endoplasmic reticulum (green) of HEK cells (red plasma membrane). Golenbock and colleagues (p. 190) show that TLR9 translocates from the endoplasmic reticulum to lysosomal compartments for ligand binding and signal transduction.

  • The proteome universe may be best represented by the peptides caught by major histocompatibility complex proteins. Unusual peptides, such as the post-translationally spliced example seen by the authors of a recent Nature paper, would not be included in a protein world gleaned only from genomics.
