CC -!- FUNCTION: Endonuclease that cooperates with the MRE11-RAD50-NBN (MRN)
CC complex in DNA-end resection, the first step of double-strand break
CC (DSB) repair through the homologous recombination (HR) pathway (By
CC similarity). HR is restricted to S and G2 phases of the cell cycle and
CC preferentially repairs DSBs resulting from replication fork collapse
CC (By similarity). Key determinant of DSB repair pathway choice, as it
CC commits cells to HR by preventing classical non-homologous end-joining
CC (NHEJ) (By similarity). Functions downstream of the MRN complex and
CC ATM, promotes ATR activation and its recruitment to DSBs in the S/G2
CC phase facilitating the generation of ssDNA (By similarity). Component
CC of the BRCA1-RBBP8 complex that regulates CHEK1 activation and controls
CC cell cycle G2/M checkpoints on DNA damage (By similarity). During
CC immunoglobulin heavy chain class-switch recombination, promotes
CC microhomology-mediated alternative end joining (A-NHEJ) and plays an
CC essential role in chromosomal translocations (PubMed:21131978,
CC PubMed:21131982). {ECO:0000250|UniProtKB:Q99708,
CC ECO:0000269|PubMed:21131978, ECO:0000269|PubMed:21131982}.
CC -!- SUBUNIT: Homodimer; dimerizes via the coiled coil domain. Interacts
CC (via the PXDLS motif) with CTBP1; the interaction is disrupted via
CC binding of the adenovirus E1A to CTBP1. Component of the BRCA1-RBBP8
CC complex. Interacts (the Ser-326 phosphorylated form) with BRCA1 (via
CC the C-terminal BRCA1 domains): the interaction occurs in the G2 phase,
CC ubiquitinates RBBP8 and involves RBBP8 in BRCA1-dependent G2/M
CC checkpoint control on DNA damage. Interacts with RB1. Interacts with
CC the MRN complex. Interacts directly with MRE11; the interaction is
CC required for efficient homologous recombination (HR) and regulation of
CC the MRN complex. Interacts directly with RAD50. Interacts directly with
CC NBN. Interacts with LM04 (via the LIM zinc-binding 1 domain). Interacts
CC with SIAH1. Interacts with RNF138. Interacts with EXD2. Interacts with
CC CUL3 and KLHL15; this interaction leads to RBBP8 proteasomal
CC degradation. Directly interacts with PIN1; this interaction depends
CC upon RBBP8 phosphorylation, predominantly at Thr-315. Interacts with
CC FZR1; this interaction leads to APC/C-mediated RBBP8 proteasomal
CC degradation. Interacts with AUNIP; leading to recruit RBBP8 to sites of
CC DNA damage. Interacts with SAMHD1 (By similarity). Interacts with
CC HDGFL2 (By similarity). {ECO:0000250|UniProtKB:Q99708}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q99708}.
CC Chromosome {ECO:0000250|UniProtKB:Q99708}. Note=Associates with sites
CC of DNA damage in S/G2 phase. Ubiquitinated RBBP8 binds to chromatin
CC following DNA damage. {ECO:0000250|UniProtKB:Q99708}.
CC -!- DOMAIN: The damage-recruitment motif is required for DNA binding and
CC translocation to sites of DNA damage. {ECO:0000250}.
CC -!- DOMAIN: The PXDLS motif binds to a cleft in CtBP proteins.
CC {ECO:0000250|UniProtKB:Q99708}.
CC -!- PTM: Hyperphosphorylation upon ionizing radiation results in
CC dissociation from BRCA1. Phosphorylation at Thr-843 by CDK1 is
CC essential for the recruitment to DNA and the DNA repair function.
CC Phosphorylated at Ser-326 as cells enter G2 phase. This phosphorylation
CC is required for binding BRCA1 and for the G2/M DNA damage transition
CC checkpoint control (By similarity). Phosphorylation at Thr-315 is
CC required for PIN1-binding, while phosphorylation at Ser-276 serves as a
CC PIN1 isomerization site. Phosphorylation at Thr-315 is cell-cycle
CC dependent. It steadily increases during S phase, peaks at late S/G2
CC phase, and drops at G1 (By similarity). {ECO:0000250|UniProtKB:Q99708}.
CC -!- PTM: Ubiquitinated. Ubiquitination at multiple sites by BRCA1 (via its
CC N-terminal RING domain) does not lead to its proteasomal degradation
CC but instead the ubiquitinated RBBP8 binds to chromatin following DNA
CC damage and may play a role in G2/M checkpoint control. Ubiquitinated by
CC RNF138 at its N-terminus. Ubiquitinated through 'Lys-48' by the E3
CC CUL3-KLHL15 complex; this modification leads to proteasomal
CC degradation. Ubiquitinated by the E3 FZR1/APC/C complex; this
CC modification leads to proteasomal degradation.
CC {ECO:0000250|UniProtKB:Q99708}.
CC -!- SIMILARITY: Belongs to the COM1/SAE2/CtIP family. {ECO:0000305}.
CC -!- CAUTION: Upon DNA damage, was shown to interact with SIRT6 resulting in
CC its deacetylation. However, this study was later retracted.
