RbAp46: Lysates

RBBP7 antibody, also known as RbAp46 (Retinoblastoma protein associated protein 46), is a nuclear protein that has been shown to interact directly with retinoblastoma protein and is a component of the mSin3 corepressor complex, as are the histone deacetylase proteins (HDACs). It shares about 75% sequence identity with the closely related RbAp48, and appears to be functionally related to the yeast MSI1 protein in that overexpression of RbAp46 suppresses heat shock sensitivity in a RAS pathway dependent manner. RBBP7 has also been demonstrated to be up-regulated by the Wilms' tumor suppressor gene product, WT1. In addition, cells transfected with this antibody have shown strong inhibition of growth.
