Switch #:
SWTI000186
Switch type:
Binary
Switch subtype:
Physicochemical compatibility

Description:
Phosphorylation of S198 in the NES of M-phase inducer phosphatase 3 (CDC25C) by Serine/threonine-protein kinase PLK1 (PLK1) inhibits binding to Exportin-1 (XPO1), thus promoting nuclear localization of M-phase inducer phosphatase 3 (CDC25C).

Participants:
(1) M-phase inducer phosphatase 3 (CDC25C)
(2) Exportin-1 (XPO1)

Interactions
Interaction #1 CDC25C - XPO1

Interfaces
(1) TRG_NES_CRM1_1 motif (189EISDELMEFSLKDQE203) in M-phase inducer phosphatase 3 (CDC25C)
(2) Exportin 1-like protein (123-268) in Exportin-1 (XPO1)

Interaction Regulation
PTM-dependent Abrogation (Phosphorylation of S198 on M-phase inducer phosphatase 3 (CDC25C)) of the M-phase inducer phosphatase 3 (CDC25C) TRG_NES_CRM1_1 motif - Exportin-1 (XPO1) Exportin 1-like protein interaction

Regulatory Enzymes for switch
Modifying enzymes for residue: S198: Serine/threonine-protein kinase PLK1 (PLK1)
