Lipid raft microdomain compartmentalization of TC10 is required for insulin signaling and GLUT4 translocation. [PDF]
, 2001 Recent studies indicate that insulin stimulation of glucose transporter (GLUT)4 translocation requires at least two distinct insulin receptor-mediated signals: one leading to the activation of phosphatidylinositol 3 (PI-3) kinase and the other to the ...

Deconstruction of the Ras switching cycle through saturation mutagenesis
eLife, 2017 Ras proteins are highly conserved signaling molecules that exhibit regulated, nucleotide-dependent switching between active and inactive states. The high conservation of Ras requires mechanistic explanation, especially given the general mutational ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A Comparative Analysis of Individual RAS Mutations in Cancer Biology
Frontiers in Oncology, 2019 In human cells, three closely related RAS genes, termed HRAS, KRAS, and NRAS, encode four highly homologous proteins. RAS proteins are small GTPases involved in a broad spectrum of key molecular and cellular activities, including proliferation and ...

Ras-GRF Activates Ha-Ras, but Not N-Ras or K-Ras 4B, Proteinin Vivo [PDF]
Journal of Biological Chemistry, 1998 Human cells contain four homologous Ras proteins, but it is unknown whether these homologues have different biological functions. As a first step in determining if Ras homologues might participate in distinct signaling cascades, we assessed whether a given Ras guanine nucleotide exchange factor could selectively activate a single Ras homologue in vivo.
