    AMPylation matches BiP activity to client protein load in the endoplasmic reticulum

    Steffen Preissler et al.
    Attaching a molecule of adenosine mono-phosphate (AMP) to the BiP protein at threonine 518 regulates its chaperone activity in the endoplasmic reticulum.

    Alkylative damage of mRNA leads to ribosome stalling and rescue by trans translation in bacteria

    Erica N Thomas et al.
    Alkylation stress modify mRNAs and results in translation arrest, which activates the ribosome-rescue pathway of trans translation in bacteria.

    SIRT2 and lysine fatty acylation regulate the transforming activity of K-Ras4a

    Hui Jing et al.
    A new post-translational regulatory mechanism of K-Ras is identified, which expands the function of reversible protein lysine fatty acylation and offers new possibility to target the K-Ras oncoprotein.

    Glycine acylation and trafficking of a new class of bacterial lipoprotein by a composite secretion system

    Christopher Icke et al.
    AatD is a novel acyltransferase that mediates N-palmitoylation of glycine, a process not previously described, that results in the secretion of lipoproteins to the bacterial cell surface.

    Adaptation to constant light requires Fic-mediated AMPylation of BiP to protect against reversible photoreceptor degeneration

    Andrew T Moehlman et al.
    Tuning of BiP activity by Fic-mediated AMPylation is required for Drosophila photoreceptor plasticity and attenuation of the unfolded protein response.

    Allosteric fine-tuning of the conformational equilibrium poises the chaperone BiP for post-translational regulation

    Lukasz Wieteska et al.
    The molecular chaperone BIP from the endoplasmic reticulum is fine-tuned postranslationally through the thermodynamic and kinetic alterations in its conformational ensemble of functionally and structurally distinct physiological forms.

    Obesity-linked suppression of membrane-bound O-acyltransferase 7 (MBOAT7) drives non-alcoholic fatty liver disease

    Robert N Helsley et al.
    Loss of function of membrane-bound O-acyltransferase 7 (MBOAT7), but not transmembrane channel-like 4 (TMC4), promotes hepatic steatosis.

    Cellular encoding of Cy dyes for single-molecule imaging

    Lilia Leisle et al.
    Cyanine fluorophores are encoded as non-canonical amino acids to produce functional proteins in cell-free translation systems and live cells for single-molecule imaging.
