(2) E3 ubiquitin-protein ligase CBL (CBL)

Interactions

Interaction #1 EGFR - CBL

Interfaces
(1) ELM:LIG_TKB motif (₁₀₆₉YSSDPT₁₀₇₄) in Epidermal growth factor receptor (EGFR)
(2) E3 ubiquitin-protein ligase CBL (CBL)

Interaction Regulation
PTM-dependent Induction (Phosphorylation of Y₁₀₆₉ on Epidermal growth factor receptor (EGFR)) of the Epidermal growth factor receptor (EGFR) LIG_TKB motif - E3 ubiquitin-protein ligase CBL (CBL) interaction
