Phosphorylation of T1269 in the PDZ-binding motif of Breakpoint cluster region protein (BCR) inhibits its interaction with the Afadin (MLLT4) protein.

(1) Breakpoint cluster region protein (BCR)
(2) Afadin (MLLT4)

Interaction #1 BCR - MLLT4

(1) LIG_PDZ_Class_1 motif (1266LFSTEV1271) in Breakpoint cluster region protein (BCR)
(2) PDZ domain (Also known as DHR or GLGF) (1008-1090) in Afadin (MLLT4)

Interaction Regulation
PTM-dependent Abrogation (Phosphorylation of T1269 on Breakpoint cluster region protein (BCR)) of the Breakpoint cluster region protein (BCR) LIG_PDZ_Class_1 motif - Afadin (MLLT4) PDZ domain (Also known as DHR or GLGF) interaction

Additional Information
Affinity : BCR (Wild type): 85.9 µM, BCR (T1269D mutant): >1000 µM
