The Signaling Gateway’s Molecule of the Week is Rsk1, or to give it its full name, p90 ribosomal S6 kinase. Rsk1 is a serine kinase that phosphorylates the 40S ribosomal protein S6 in response to Ras/extracellular signal-regulated kinase pathway activation. Rsk1 has a role in gene transcription, cell growth and proliferation, and cell survival. The full characterization of Rsk1 can be seen at its peer-reviewed Molecule Pages
