Description:
Phosphorylation of S327 in the BRCT-binding motif of DNA endonuclease RBBP8 (RBBP8) induces binding to the Breast cancer type 1 susceptibility protein (BRCA1) protein.

Participants:
(1) DNA endonuclease RBBP8 (RBBP8)
(2) Breast cancer type 1 susceptibility protein (BRCA1)

Interactions
Interaction #1 RBBP8 - BRCA1

Interfaces
(1) LIG_BRCT_BRCA1_1 motif (326SSPVF330) in DNA endonuclease RBBP8 (RBBP8)
(2) BRCA1 C Terminus (BRCT) domain (1648-1723) and (1756-1842) in Breast cancer type 1 susceptibility protein (BRCA1)

Interaction Regulation
PTM-dependent Induction (Phosphorylation of S327 on DNA endonuclease RBBP8 (RBBP8)) of the DNA endonuclease RBBP8 (RBBP8) LIG_BRCT_BRCA1_1 motif - Breast cancer type 1 susceptibility protein (BRCA1) BRCA1 C Terminus (BRCT) domain interaction
