To conclude, our data indicated that TCTP participated in rumen papillae growth by promoting rumen stratum basale cell proliferation.The hexapeptide 306VQIVYK311 (PHF6) plays an important role in the aggregation of Tau protein, which is a hallmark of the Alzheimer's disease (AD). In this article, we systematically compare the effects of eight popular all-atom force fields on the monomeric and fibrillar PHF6 in the molecular dynamics (MD) simulations, which could be helpful in the computer-aided drug design against PHF6. We show that the fibrillar PHF6 prefers β-strand-like structures in all the force fields while the monomer has different structural preferences depending on the force fields. The interactions for stabilizing the fibril are further investigated. In the end, according to the interactions revealed by NMR and the stability of the fibril in the literature, we benchmark the force fields.The signal recognition particle (SRP) plays an essential role in protein translocation across biological membranes. Stable complexation of two GTPases in the signal recognition particle (SRP) and its receptor (SR) control the delivery of nascent polypeptide to the membrane translocon. In archaea, protein targeting is mediated by the SRP54/SRP19/7S RNA ribonucleoprotein complex (SRP) and the FtsY protein (SR). In the present study, using fluorescence resonance energy transfer (FRET), we demonstrate that archaeal 7S RNA stabilizes the SRP54·FtsY targeting complex (TC). Moreover, we show that archaeal SRP19 further assists 7S RNA in stabilizing the targeting complex (TC). These results suggest that archaeal 7S RNA and SRP19 modulate the conformation of the targeting complex and thereby reinforce TC to execute protein translocation via concomitant GTP hydrolysis.A newly-emergent beta-coronavirus, SARS-
