Signal Transduction Can Regulate Gene Expression
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A signaling pathway can regulate gene expression when its final activated protein enters the nucleus and controls transcription or translation there.
Show
A phosphorylated inhibitor protein can release a bound transcription factor, letting that factor enter the nucleus and switch on RNA transcription.
Watch for
Only the pathway's final, nucleus-bound step directly changes gene expression — the earlier cascade steps only relay the signal there.
