Retinoblastoma-binding protein 8 is a protein that in humans is encoded by the RBBP8 gene.[5][6][7]

Function

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.[7]

Interactions

RBBP8 has been shown to interact with:

ATM,[8][9]
BRCA1,[8][10][11][12][13][14][15]
CTBP1,[10][16]
LMO4,[17][18]
RB1,[5][19]
RBL1,[5][20]
RBL2,[5][21] and
SIAH1[22]
