Retinoblastoma Description
1F8 recognizes a 105 kDa phosphoprotein, identified as retinoblastoma (Rb) gene product. The epitope is localized between aa703-772 of human Rb protein. It shows no cross-reaction with p107 or p300. The retinoblastoma gene product has been shown to play a key role in cell cycle control and is known as a tumor suppressor gene. Loss of its function leads to tumor development. It is widely expressed in a variety of human tissues including mammary carcinoma, esophageal cancer, squamous cell carcinoma and cervical cancer.
