Switches

This ELM instance is part of the following 2 switching mechanisms annotated at the switches.ELM resource:

SWTI000315:

Inhibition of nuclear import of Large T antigen by phosphorylation-dependent (T124) binding of BRCA1-associated protein (BRAP).
SWTI000329:

An intramolecular interaction between the importin beta-binding (IBB) domain and the NLS-binding pocket of Importin subunit alpha (SRP1) prevents binding of NLS cargo (e.g. Large T antigen) in the absence of Importin subunit beta-1 (KAP95) by hiding of the NLS-binding pocket. Binding of the IBB of Importin subunit alpha (SRP1) to Importin subunit beta-1 (KAP95) relieves this auto-inhibitory interaction and increases the affinity of Importin subunit alpha (SRP1) for NLS cargo.
