[...]the nucleus has a double membrane punctured by nuclear pores, nuclear pore complexes (NPCs) that fill these pores, a nucleolus responsible for ribosomal RNA transcription and ribosome assembly, heterochromatin, Cajal bodies, and other nuclear subdomains, together with a filamentous lamina subtending the NE, all of which appear to be highly conserved nuclear features. Relationships are based on recent views of the branching order but should not be considered definitive. https://doi.org/10.1371/journal.ppat.1006170.g001 For example, by negative stain electron microscopy, the NPCs of organisms across the range of eukaryotes are extremely similar, bearing 8-fold symmetry and roughly similar dimensions. Ribosome profiling reveals translation control as a key mechanism generating differential gene expression in Trypanosoma cruzi. Chromatin Proteomics Reveals Variable Histone Modifications during the Life Cycle of Trypanosoma cruzi. The Trypanosoma brucei AIR9-like protein is cytoskeleton-associated and...
