Source / Purification
Phospho-Rb (Ser780) (D59B7) Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser780 of human Rb protein. Phospho-Rb (Ser807/811) (D20B12) XP® Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser807/811 of human Rb protein. Rb (4H1) monoclonal antibody is produced by immunizing animals with Rb-C Fusion Protein #6022, which contains residues 701-928 of human Rb .
Product Description
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).
