Switch #:
SWTI000609
Switch type:
Binary
Switch subtype:
Pre-translational

Description:
Alternative splicing removes the nuclear export signal (NES) of Catenin delta-1 (CTNND1), abrogating binding to Exportin-1 (XPO1). Despite demonstration of the importance of the NES for removing Catenin delta-1 (CTNND1) from the nucleus, those isoforms without NES are rarely found in the nucleus.

Participants:
(1) Catenin delta-1 (CTNND1)
(2) Exportin-1 (XPO1)

Interactions
Interaction #1 CTNND1 - XPO1

Interfaces
(1) TRG_NES_CRM1_1 motif (942ESLEEELDVLVLDDE956) in Catenin delta-1 (CTNND1)
(2) Exportin 1-like protein (123-268) in Exportin-1 (XPO1)

Interaction Regulation
Alternative splicing Abrogation of the Catenin delta-1 (CTNND1) TRG_NES_CRM1_1 motif - Exportin-1 (XPO1) Exportin 1-like protein interaction
