Differential protein-protein interactions underlie signaling mediated by the TCR and a 4-1BB domain-containing CAR
Sci Signal. 2024 Mar 5;17(826):eadd4671. doi: 10.1126/scisignal.add4671. Epub 2024 Mar 5.ABSTRACTCells rely on activity-dependent protein-protein interactions to convey biological signals. For chimeric antigen receptor (CAR) T cells containing a 4-1BB costimulatory domain, receptor engagement is thought to stimulate the formation of protein complexes similar to those stimulated by T cell receptor (TCR)-mediated signaling, but the number and type of protein interaction-mediating binding domains differ between CARs and TCRs. Here, we performed coimmunoprecipitation mass spectrometry analysis of a second-generation, CD19-dire...

eEF1A2 promotes PTEN-GSK3 β-SCF complex-dependent degradation of Aurora kinase A and is inactivated in breast cancer
Sci Signal. 2024 Mar 5;17(826):eadh4475. doi: 10.1126/scisignal.adh4475. Epub 2024 Mar 5.ABSTRACTThe translation elongation factor eEF1A promotes protein synthesis. Its methylation by METTL13 increases its activity, supporting tumor growth. However, in some cancers, a high abundance of eEF1A isoforms is associated with a good prognosis. Here, we found that eEF1A2 exhibited oncogenic or tumor-suppressor functions depending on its interaction with METTL13 or the phosphatase PTEN, respectively. METTL13 and PTEN competed for interaction with eEF1A2 in the same structural domain. PTEN-bound eEF1A2 promoted the ubiquitination an...

ALOX5 drives the pyroptosis of CD4 < sup > + < /sup > T cells and tissue inflammation in rheumatoid arthritis
Sci Signal. 2024 Feb 27;17(825):eadh1178. doi: 10.1126/scisignal.adh1178. Epub 2024 Feb 27.ABSTRACTPyroptosis, an inflammatory form of programmed cell death, is linked to the pathology of rheumatoid arthritis (RA). Here, we investigated the molecular mechanism underlying pyroptosis in T cells isolated from patients with RA. Compared with healthy individuals, patients with RA had more pyroptotic CD4+ T cells in blood and synovia, which correlated with clinical measures of disease activity. Moreover, the mRNA expression and protein abundance of arachidonate 5-lipoxygenase (ALOX5), which converts arachidonic acid to leukotrie...

Multiomic profiling of breast cancer cells uncovers stress MAPK-associated sensitivity to AKT degradation
Sci Signal. 2024 Feb 27;17(825):eadf2670. doi: 10.1126/scisignal.adf2670. Epub 2024 Feb 27.ABSTRACTMore than 50% of human tumors display hyperactivation of the serine/threonine kinase AKT. Despite evidence of clinical efficacy, the therapeutic window of the current generation of AKT inhibitors could be improved. Here, we report the development of a second-generation AKT degrader, INY-05-040, which outperformed catalytic AKT inhibition with respect to cellular suppression of AKT-dependent phenotypes in breast cancer cell lines. A growth inhibition screen with 288 cancer cell lines confirmed that INY-05-040 had a substantial...
