Phosphorylation of T779 in the PTB-binding motif of Integrin beta-3 (ITGB3) inhibits its interaction with SHC-transforming protein 1 (SHC1).

(1) Integrin beta-3 (ITGB3)
(2) SHC-transforming protein 1 (SHC1)

Interaction #1 ITGB3 - SHC1

(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 Abrogation (Phosphorylation of T779 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

Additional Information
