The nucleocytoplasmic transport processes are mediated by soluble transport factors constantly navigating between nuclear and cytoplasmic compartments. Our understanding about nuclear export of general 'nuclear import factors' that deliver the cargo to the nucleus is still fragmentary. Utilizing green fluorescent protein tagged glucocorticoid receptor (GR) and relA as our working model and with judicious use of LMB, we show in living cells that all the soluble components of the nuclear import machinery exit nucleus via exportin1/CRM1 independent pathway(s).
