Abstract:
Tourrière et al. (2013. J. Cell Biol. https://doi.org/10.1083/jcb.200212128) reported that G3BP1-S149 dephosphorylation promotes stress granule formation. We show that constructs used to establish this conclusion contain additional mutations causing these phenotypes, and that S149 phosphorylation status does not change upon stress.
