    Specificity / Sensitivity

    Phospho-Rb (Ser780) (C84F6) Rabbit mAb detects endogenous levels of total Rb protein only when phosphorylated at Ser780.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to resudues surrounding Ser780 of human Rb protein.

    Western Blotting

    Western Blotting

    Background

    The retinoblastoma tumor suppressor protein, Rb, regulates cell proliferation by controlling progression through the restriction point within the G1-phase of the cell cycle (1). Rb has three functionally distinct binding domains and interacts with critical regulatory proteins including the E2F family of transcription factors, c-Abl tyrosine kinase, and proteins with a conserved LXCXE motif (2-4). Cell cycle-dependent phosphorylation by a CDK inhibits Rb target binding and allows cell cycle progression (5). Rb inactivation and subsequent cell cycle progression likely requires an initial phosphorylation by cyclin D-CDK4/6 followed by cyclin E-CDK2 phosphorylation (6). Specificity of different CDK/cyclin complexes has been observed in vitro (6-8) and cyclin D1 is required for Ser780 phosphorylation in vivo (9).
