In eukaryotes, termination of translation is controlled by polypeptide chain release factors eRF1 and eRF3, of which the former recognizes nonsense codons, while the latter interacts with eRF1 and stimulates polypeptide release from the ribosome in a GTP‐ dependent manner, and ABCE1, which facilitates ribosome recycling. In this work, we demonstrate that Pub1, a yeast protein known to be involved...
Amyloids and prions represent aggregates of misfolded proteins, which consist of protein polymer fibrils with cross-beta sheet structure. Understanding of their occurrence and role is developing rapidly. Initially, they were found associated with mammalian diseases, mainly of neurodegenerative nature. Now they are known to relate to a range of non-disease phenomena in different species from mammals...
The fibrinogen molecule consists of two sets of Aα, Bβ, and γ chains assembled into a bilateral disulfide linked (Aα, Bβ, γ) 2 structure. Cleavage of the two A-fibrinopeptides (FPA, Aα1-16) from normal Aα chains with arginine at position 16 (R FPA ) by thrombin or the venom enzyme atroxin transforms fibrinogen into self-aggregating fibrin monomers (α, Bβ, γ) 2 . Mutant...
