Background: RB1

Retinoblastoma 1 protein (RB-1; also retinoblastoma-associated protein, pp110, and p105-Rb) is a 110 kDa tumor suppressor gene and member of the retinoblastoma protein family. Human RB-1 is 928 amino acids in length. The protein contains a Pocket domain (aa 373-771), which is comprised of two other domains, domain A (aa 373-573) and domain B (aa 640-771), and a “spacer” (aa 580-639). The Pocket domain binds to threonine-phosphorylated domain C (aa 771-928), which thereby prevents interaction with heterodimeric E2F/DP transcription factor complexes. Human RB-1 is 90% aa identical to mouse RB-1. RB-1 is expressed in the retina. The underphosphorylated, active form of RB-1 interacts with E2F1 and represses its transcription activity, leading to cell cycle arrest. Defects in RB-1 lead to the childhood cancer retinoblastoma.
