RB1 phosphorylated on S612 is active. 2 / 2

"These results suggest that ser612 is phosphorylated by chk1/2 after dna damage, leading to the formation of prb-e2f-1. phosphorylation of prb at ser612 enhanced the formation of a complex between prb and e2f-1"

"Phosphorylation of prb at ser612 by chk1/2 leads to a complex between prb and e2f-1 after dna damageprb inhibits cell cycle progression through interactions with the e2f family of transcription factors. Here, we report that dna damage induced not only the dephosphorylation of prb at cdk phosphorylation sites and the binding of prb to e2f-1, but also the phosphorylation of prb at ser612. Phosphorylation of prb at ser612 enhanced the formation of a complex between prb and e2f-1"
