Trans-species polymorphism at primate Major Histocompatibility Complex genes is old, especially in the 'classical' genes, while rapidly-evolving regions of each gene correspond with proteins' functional domains.
Inhibition of the UFD-1-NPL-4 complex activates immune responses in Caenorhabditis elegans that reduce gut pathogen load but simultaneously compromise host survival.
Primate cross-species analysis of interactions between transposable elements and KRAB-ZNF genes with the new TEKRABber tool highlights human-specific interactions with potential relevance to Alzheimer’s disease.

A hitherto unrecognized superfamily of enzymes identified here provides unifying insights spanning lipid metabolism, anti-viral and anti-bacterial immunity, and the origin of developmental regulators like Wnt.

CTCF binding promotes chromatin-nuclear speckle interactions and gene activation after DNA demethylation, yet its binding and looping patterns are unaffected by speckle depletion.
WRN and WRNP1 ATPases together with WRN 3’ to 5’ exonuclease raise the fidelity of intrinsically highly error-prone Y-family DNA polymerases such that they perform error-free translesion synthesis.
