Claim: RBBP7, a type of large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues, belongs to a highly conserved subfamily of WD-repeat proteins and is found among several proteins that binds directly to retinoblastoma protein.
Evidence: Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Histone-binding protein RBBP7 is a protein that in humans is encoded by the RBBP7 gene. This protein is a ubiquitously expressed nuclear protein and belongs to a highly conserved subfamily of WD-repeat proteins. It is found among several proteins that binds directly to retinoblastoma protein, which regulates cell proliferation.
