    Pharmacological dimerization and activation of the exchange factor eIF2B antagonizes the integrated stress response

    Carmela Sidrauski et al.
    A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

    Quantitative H2S-mediated protein sulfhydration reveals metabolic reprogramming during the integrated stress response

    Xing-Huang Gao et al.
    ATF4, the master regulator of transcription during the Integrated Stress Response (ISR), causes global changes in cysteine sulfhydration of proteins and this event causes cellular metabolic reprogramming.

    Actin dynamics tune the integrated stress response by regulating eukaryotic initiation factor 2α dephosphorylation

    Joseph E Chambers et al.
    Monomeric actin forms a crucial component of the eIF2α holophosphatase linking the integrated stress response to actin polymeric status.

    Inhibiting the integrated stress response pathway prevents aberrant chondrocyte differentiation thereby alleviating chondrodysplasia

    Cheng Wang et al.
    Integrated stress response-induced expression of ATF4 and its transactivation of SOX9 causes aberrant chondrocyte differentiation and skeletal defects which can be alleviated by modulating initiation-factor eIF2α phosphorylation translation control.

    Cap-proximal nucleotides via differential eIF4E binding and alternative promoter usage mediate translational response to energy stress

    Ana Tamarkin-Ben-Harush et al.
    Differential eIF4E binding to transcription initiation nucleotides and alternative promoter usage of eIF1A, PABP and other genes are involved in the response of the translation machinery to energy stress.

    DNA Replication: A new role for a tumor-suppressing protein

    Jeremy S Setton, Simon N Powell
    In addition to its role in preventing tumors, the protein p53 appears to participate in a DNA repair process known as the replication-stress response.
