WebOne of the hallmarks of Alzheimer's disease (AD) is the neurofibrillary tangle (NFT), of which the long-lived protein tau is a primary component. Although tau and its relationship to AD has been studied extensively, isomerization in tau has received relatively little attention, and the connection between tau isomerization and AD remains unexplored. WebBesides histones and Nups, several other long-lived proteins are engaged in clear stable structures, such as collagens in the extracellular matrix, lamins in the nuclear lamina and proteins of the myelin sheath. Some long-lived proteins, however, lacked association with any apparent stable structures and include the enzymes Sirt2, Enpp6, and Cnp1.

Here, … WebDry seeds contain translatable, long-lived mRNAs that are stored during seed maturation. Early studies using transcriptional inhibitors supported the view that protein synthesis during the initial phase of germination occurs on long-lived mRNA templates.

WebAutophagy is a cellular response to starvation that generates autophagosomes to carry long-lived proteins and cellular organelles to lysosomes for degradation. Activation of autophagy by viruses can provide an innate defense against infection, and for (+) strand RNA viruses autophagosomes can facilitate assembly of replicase proteins.
