Signal pathways activate transcription factors for their transpo into the nucleus by all except
Impoin carrier molecule is not activated Reference: Harper; 30th edition
Detachment of the transcription factor from a complexing protein can unmask a nuclear localisation signal
Phosphorylation of impoin protein increases its binding affinity for transcription factors
Phosphorylation of the transcription factor can increase its impoin binding affinity
Dephosphorylation of the transcription factor can increase its impoin binding affinity
Structure and function of protein
