What is Cell Signaling?

Cell signaling (additionally called signal transduction) refers back to the processes by using which cells detect and respond to external or inner cues. These cues can be:

• Chemical signals (hormones, growth elements, cytokines)
• Physical indicators (mechanical pressure, mild, temperature)
• Intracellular changes (DNA damage, metabolic shifts)

The cell converts these alerts into responses thru receptors, intracellular signaling cascades (often regarding kinases, phosphatases), 2d messengers, transcription factors, and downstream effector proteins. Importantly, signaling is tightly regulated at multiple stages inclusive of post translational modifications (PTMs), spatial localization, comments loops, and ligand/receptor interactions.
