Cytoplasmic processing bodies
WebAug 16, 2024 · RNA processing bodies (P-bodies) are non-membranous cytoplasmic aggregates of mRNA and proteins involved in mRNA decay and translation repression. P-bodies actively respond to environmental stresses, associated with another type of RNA granules, known as stress granules (SGs). Alphaviruses were previously shown to block … WebJul 1, 2015 · Ge-1 is a central component of the mammalian cytoplasmic mRNA processing body. RNA (2005) A. Eulalio et al.
