Reporting Avenues for Concerns Related to Integrity or Fairness

The Receptor Biology and Signal Transduction (RBST) Study Section focuses on basic molecular mechanisms of receptor mediated cellular signaling. The applications involve pharmacological, physiological, and neurochemical studies of cell surface receptors including G-protein coupled receptors (GPCRs), ion channel receptors, and enzyme-linked receptors and their regulation. The study section also reviews post-translational modifications, second messengers, kinases, phosphatases and calcium regulatory mechanisms associated with signal transduction as well as cross-talk with other pathways. The studies may involve a variety of model systems including all cell types, uni- or multi-cellular organisms.
