Signal transduction is a crucial biological process where external signals are converted into cellular responses. It begins with signal molecules binding to receptors on the cell membrane, triggering a cascade of effects inside the target cell. This intricate interplay governs numerous physiological functions, enabling cells to adapt to their environment and communicate effectively. Understanding these mechanisms is fundamental in fields like pharmacology, cancer research, and cellular biology, paving the way for therapeutic advancements.
