Signalointireitti refers to the signaling pathway within a biological system. These pathways are crucial for cell communication, enabling cells to respond to external stimuli and internal changes. A signaling pathway typically involves a series of molecular interactions, starting with a signal molecule, such as a hormone or neurotransmitter, binding to a receptor on the cell surface. This binding event triggers a cascade of events inside the cell, often involving the activation or deactivation of specific proteins.
The signal is relayed through a chain of intracellular molecules, each step amplifying or modifying the signal.
