Signal Transduction

---

Signal transduction is the process by which cells receive and respond to signals from their environment. It involves the transmission of information from the outside of the cell to the inside, where it can trigger a response. This process is essential for many cellular functions, including growth, differentiation, and survival. Signal transduction pathways often involve the activation of protein kinases and the phosphorylation of target proteins, leading to changes in gene expression and cellular behavior. Dysregulation of signal transduction pathways can contribute to a variety of diseases, including cancer and metabolic disorders.
