CST, 13152V2, PathScan® Phospho-Rb (Ser807/811) Sandwich ELISA Kit

ELISA Kit for studying Rb (Ser807/Ser811) phosphate in the research area. Protocol Available protocols: ELISA+ Specificity / Sensitivity PathScan Species Reactivity: Human 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 (6-8) and cyclin D1 is required for Ser780 phosphorylation (9).
