(2) SHC-transforming protein 1 (SHC1)

Interactions
Interaction #1 ITGB3 - SHC1

Interfaces
(1) LIG_PTB_Phospho_1 motif (779TFTNITY785) in Integrin beta-3 (ITGB3)
(2) Phosphotyrosine interaction domain (PTB/PID) (162-318) in SHC-transforming protein 1 (SHC1)

Interaction Regulation
PTM-dependent Induction (Phosphorylation of Y785 on Integrin beta-3 (ITGB3)) of the Integrin beta-3 (ITGB3) LIG_PTB_Phospho_1 motif - SHC-transforming protein 1 (SHC1) Phosphotyrosine interaction domain (PTB/PID) interaction
