Signal Transduction Purity

Meaning

Signal Transduction Purity describes the precision and specificity of the intracellular cascade of biochemical events initiated when an extracellular messenger, such as a hormone or growth factor, binds to its cognate receptor. High purity means the signal is accurately and efficiently transmitted through the intended pathway without activating off-target or competing cellular responses. This clarity of signaling is vital for precise cellular function and avoiding pathological cross-talk between pathways. Reduced purity leads to cellular dysfunction and noise.
