Background: The protein encoded by this gene is a ubiquitously expressed nuclear protein. It is found among several proteins that bind directly to retinoblastoma protein, which regulates cell proliferation. This protein complexes with transcriptional co-repressor CTBP. It is also associated with BRCA1 and is thought to modulate the functions of BRCA1 in transcriptional regulation, DNA repair, and/or cell cycle checkpoint control. It is suggested that this gene may itself be a tumor suppressor acting in the same pathway as BRCA1. Three transcript variants encoding two different isoforms have been found for this gene. More transcript variants exist, but their full-length natures have not been determined.
Storage: Store at -20℃. Avoid freeze / thaw cycles.
Recommended Dilutions: WB 1:500 - 1:2000

Target (Information from UniProt)
Function: Endonuclease that cooperates with the MRE11-RAD50-NBN (MRN) complex in DNA-end resection, the first step of double-strand break (DSB) repair through the homologous recombination (HR) pathway. HR is restricted to S and G2 phases of the cell cycle and preferentially repairs DSBs resulting from replication fork collapse. Key determinant of DSB repair pathway choice, as it commits cells to HR by preventing classical non-homologous end-joining (NHEJ). Functions downstream of the MRN complex and ATM, promotes ATR activation and its recruitment to DSBs in the S/G2 phase facilitating the generation of ssDNA. Component of the BRCA1-RBBP8 complex that regulates CHEK1 activation and controls cell cycle G2/M checkpoints on DNA damage (PubMed:10764811, PubMed:10910365, PubMed:15485915, PubMed:16581787, PubMed:16818604, PubMed:17965729, PubMed:19202191, PubMed:19759395, PubMed:20064462, PubMed:20829486). During immunoglobulin heavy chain class-switch recombination, promotes microhomology-mediated alternative end joining (A-NHEJ) and plays an essential role in chromosomal translocations (By similarity).
Tissue Specificity: Expressed in ER-positive breast cancer lines, but tends to be down-regulated ER-negative cells (at protein level).
Involvement in Disease: Seckel syndrome 2: A rare autosomal recessive disorder characterized by proportionate dwarfism of prenatal onset associated with low birth weight, growth retardation, severe microcephaly with a bird-headed like appearance, and mental retardation.

Jawad syndrome: A syndrome characterized by congenital microcephaly, moderately severe mental retardation, and symmetrical digital anomalies. Digital malformations of variable degree include hallux valgus, syndactyly of toes 4 and 5, short fifth fingers, single flexion crease of fifth fingers, polydactyly and synpolydactyly.
Sequence Similarities: Belongs to the COM1/SAE2/CtIP family.
Post-Translational Modification: Acetylated. Deacetylation by SIRT6 upon DNA damage promotes DNA end resection.
Cellular Location: Nucleus. Chromosome.

Associates with sites of DNA damage in S/G2 phase (PubMed:10764811, Ref.29). Ubiquitinated RBBP8 binds to chromatin following DNA damage (PubMed:16818604).
