Retinol-binding protein 2, Cellular retinol-binding protein II, CRBP-II, RBP2, CRBP2
Rb (retinoblastoma protein) is a potent transcriptional regulator that is directly involved with events such as entry into cell division and formation of heterochromatin. RBP2 (Retinoblastoma-binding protein 2), also known as RBBP2, JARID1A (Jumonji/ARID domain-containing protein 1A) or KDM5A, is a nuclear protein that belongs to the JARID1 histone demethylase family. Expressed ubiquitously, RBP2 functions as a histone demethylase that, in conjunction with other proteins, binds directly to the viral-binding domain of Rb, thereby regulating Rb-mediated cell proliferation events. In addition, RBP2 can bind to the Rb-interacting protein rhombotin-2 (LMO2) and, through this interaction, can indirectly modulate Rb activity. Via its demethylase activity, RBP2 can remove methyl residues from Histone H3, thus playing a crucial role in the histone code. RBP2 contains one ARID domain, three PHD-type zinc fingers, one JMJN domain and one JMJC domain through which it conveys its enzymatic activity. Multiple isoforms of RBP2 exist due to alternative splicing events.
