name: retinoblastoma-like protein 2 isoform 1 phosphorylated 2
def: "A retinoblastoma-like protein 2 isoform 1 phosphorylated form that has Cdk-dependent G1 phosphorylation, and additionally phosphorylated on a Ser residue within the region linking the retinoblastoma-associated protein A and B domains, by cyclin Cdk4(6). This phosphorylation leads to ubiquitin-dependent proteolysis." [PMID:12006580, PMID:12435635]
