Signaling amplification
WebSignal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately … WebThe three main types of cell communication are autocrine, paracrine, and endocrine signaling. Direct signaling is a subtype of paracrine signaling. The steps in signal transduction are ligand-receptor binding, conformation change of the receptor, signal amplification, cellular response, and signal termination. 1.
