  1. Mascaraque V, Hernaez M, Jimenez Sanchez M, Hansen R, Gil C, Martín H, et al. Phosphoproteomic analysis of protein kinase C signaling in Saccharomyces cerevisiae reveals Slt2 mitogen-activated protein kinase (MAPK)-dependent phosphorylation of eisosome core components. Mol Cell Proteomics. 2013;12:557-74 pubmed publisher
    ..We show here that Pkc1-induced phosphorylation of the eisosome core components Pil1 and Lsp1 was not exerted directly by Pkc1, but involved signaling through the Slt2 MAPK module.
