Nucleoporin 50kD is a member of the FG-repeat containing nucleoporins that functions as a soluble cofactor in importin-alpha:beta-mediated nuclear protein import.
Pseudogenes of this gene are found on chromosomes 5, 6, and 14.
NUP50 is a tristable switch that alternates between binding modes
The C terminus binds importin-beta through RAN-GTP.
The N terminus binds the C terminus of importin-alpha, while a central domain binds importin-beta.
NUP50:importin-alpha:importin-beta binds cargo and can stimulate nuclear import.
Endogenous NUP50 can shuttle and is accessible from the cytoplasmic side of the nuclear envelope.
These findings identified NUP50 as a cofactor for importin-alpha:importin-beta nuclear import and as a subunit of the importin complex.
