Switch #:
SWTI000543
Switch type:
Binary
Switch subtype:
Pre-translational

Description:
Alternative splicing removes the nuclear localisation signal (NLS) of F-box/WD repeat-containing protein 7 (FBXW7), abrogating binding to Importin subunit alpha-1 (KPNA1). There are two other NLS motifs in the protein, meaning the isoform can still enter the nucleus.

Participants:
(1) F-box/WD repeat-containing protein 7 (FBXW7)
(2) Importin subunit alpha-1 (KPNA1)
