SWTI000070
Switch type:
Binary
Switch subtype:
Physicochemical compatibility

Description:
Phosphorylation of S208 in the Pin1-binding motif of Mothers against decapentaplegic homolog 3 (SMAD3) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein.

Participants:
(1) Mothers against decapentaplegic homolog 3 (SMAD3)
(2) Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1)

Interactions
Interaction #1 SMAD3 - PIN1

Interfaces
(1) DOC_WW_Pin1_4 motif (205PNLSPN210) in Mothers against decapentaplegic homolog 3 (SMAD3)
(2) WW domain (7-37) in Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1)

Interaction Regulation
PTM-dependent Induction (Phosphorylation of S208 on Mothers against decapentaplegic homolog 3 (SMAD3)) of the Mothers against decapentaplegic homolog 3 (SMAD3) DOC_WW_Pin1_4 motif - Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) WW domain interaction
