General description

The protein encoded by this gene is a negative regulator of the cell cycle and was the first tumor suppressor gene found. The encoded protein also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in this gene are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma.

Immunogen

A synthetic phosphorylated peptide around S795 of human RB (NP_000312.2).

Physical form

PBS with 0.02% sodium azide,50% glycerol,pH7.3.

Storage and Stability
