The data supports a model such that elevated Cdc2 activity delays the transition of Crb2 from its G1 to its G2 mode by blocking Srs2 DNA helicase and Casein Kinase 1 (Hhp1).
Title: Hyperactive Cdc2 kinase interferes with the response to broken replication forks by trapping S.pombe Crb2 in its mitotic T215 phosphorylated state.

These results suggest that the main role of Crb2 in DNA damage checkpoint signaling is recruiting Chk1 to sites of DNA lesions.
Title: Phosphorylation-dependent interactions between Crb2 and Chk1 are essential for DNA damage checkpoint.

Findings argue that binding of the Crb2 BRCT repeats to pH2AX is critical for checkpoint activity and provide new insight into the mechanisms of chromatin-mediated genome stability.
Title: Requirement for the phospho-H2AX binding module of Crb2 in double-strand break targeting and checkpoint activation.

Data show that polar interactions of Crb2 serine-548 and lysine-619 with the phosphate group of phospho-H2A (gamma-H2A) are critical for Crb2 IRIF formation and checkpoint function.
Title: BRCT domain interactions with phospho-histone H2A target Crb2 to chromatin at double-strand breaks and maintain the DNA damage checkpoint.

Structural and functional analysis of the crb2 domain reveals distinct roles in checkpoint signaling and DNA damage repair.
