| description | Retinoblastoma-binding protein 8 (RBBP8), also known as CtIP, is an endonuclease that cooperates with the MRE11-RAD50-NBN (MRN) complex in processing meiotic and mitotic double-strand breaks (DSBs) by ensuring both resection and intrachromosomal association of the broken ends [, ]. CtIP interacts with the BRCA1 tumour suppressor []. BRCA1 and CtIP are required to recruit Dna2 at DSBs in homologous recombination, ensuring robust DSB resection []. CtIP it is not a tumuor suppressor itself, instead, it can promote tumourigenesis. This is probably related to its role in the formation of chromosomal rearrangements through the microhomology-mediated end joining (MMEJ) pathway, a relatively error-prone pathway of DSB repair []. |
