Building on previous work (Skene et al., 2014), we show that a new ChIP-seq protocol provides superior resolution and ease of use at low sequence depth of coverage for generating genome-wide maps of protein binding.
Experimentally reconstructing the evolution of the molecular complex that animals use to orient the mitotic spindle establishes a simple genetic and physical mechanism for the emergence of a function essential for multicellularity.
New hybrid structure determination methods leveraging the inherent biophysical properties of a macromolecule through molecular dynamics simulations provide accurate and cost-efficient ways of achieving atomic structures from high resolution cryo-electron density maps.
In the ancestor of mammals, a multifunctional innate immune protein evolved when a mutation enhanced the protein’s pro-inflammatory activity and proteolytic regulation without disrupting the protein’s antimicrobial activity.
The evolution of the light-sensitive visual pigment rhodopsin involved functional tradeoffs that may have sacrificed rod photosensitivity for active-state protein stability to mitigate phototoxicity in tetrapods, but not in fishes.
