1 We show here that K-Ras.GTP recruits Galectin-3 (Gal-3) from the cytosol to the plasma membrane where it becomes an integral nanocluster component. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
2 Importantly, we show that the cytosolic level of Gal-3 determines the magnitude of K-Ras.GTP nanoclustering and signal output. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
3 Gal-3(V125A) interaction with K-Ras.GTP reduces K-Ras.GTP nanocluster formation, which abrogates signal output from the Raf/mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK; MEK) pathway. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
4 Gal-3(V125A) interaction with K-Ras.GTP reduces K-Ras.GTP nanocluster formation, which abrogates signal output from the Raf/mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK; MEK) pathway. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
5 Gal-3(V125A) interaction with K-Ras.GTP reduces K-Ras.GTP nanocluster formation, which abrogates signal output from the Raf/mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK; MEK) pathway. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
6 Gal-3(V125A) interaction with K-Ras.GTP reduces K-Ras.GTP nanocluster formation, which abrogates signal output from the Raf/mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK; MEK) pathway. Guanosine Triphosphate KRAS proto-oncogene, GTPase Homo sapiens
