Rb (phospho Ser807) Polyclonal Antibody

Rabbit Anti-Rb (phospho Ser807) Polyclonal Antibody

Product Specifications

Background

RB transcriptional corepressor 1 encoded by RB1 is a negative regulator of the cell cycle and was the first tumor suppressor gene found. RB transcriptional corepressor 1 also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in RB1 are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma.
