Structural basis of highly conserved ribosome recycling in eukaryotes and archaea.

abstract：:In addition to coordinating immune and inflammatory responses, NF-kappaB/Rel transcription factors control cell survival. Normally, NF-kappaB dimers are sequestered in the cytoplasm by binding to inhibitory IkappaB proteins, and can be activated rapidly by signals that induce the sequential phosphorylation and proteol...
