Rb is a tumor suppressor gene which functions as a negative regulator of the cell cycle by interacting with transcription factors including E2F-1, PU.1, ATF-2, UBF, Elf-1 and c-Abl. This ability to alter transcription is regulated by phosphorylation catalyzed by the cyclin-dependent protein kinases (cdks). Rb contains at least 16 consensus sequences for cdk phosphorylation, but the significance of all of these sites is unclear. Rb threonine-821 phosphorylation (catalyzed by cdk2) disrupts interaction with proteins containing the sequence LxCxE. Phosphorylation of this site (in addition to serines 780, 807, and 811) also disrupts binding to E2F.
