Retinoblastoma-binding protein 6 is a protein that in humans is encoded by the RBBP6 gene.^[1][2][3]

Function

The retinoblastoma tumor suppressor (pRB) protein binds with many other proteins. In various human cancers, pRB suppresses cellular proliferation and is inactivated. Cell cycle-dependent phosphorylation regulates the activity of pRB. This gene encodes a protein which binds to underphosphorylated but not phosphorylated pRB. Multiple alternatively spliced transcript variants that encode different isoforms have been found for this gene.^[3]

Interactions

RBBP6 has been shown to interact with Y box binding protein 1.^[4]
