[RAD53_YEAST] Controls S-phase checkpoint as well as G1 and G2 DNA damage checkpoints. Phosphorylates proteins on serine, threonine, and tyrosine. Prevents entry into anaphase and mitotic exit after DNA damage via regulation of the Polo kinase CDC5. Seems to be involved in the phosphorylation of RPH1.[1][2][3][4][5] [PIN4_YEAST] Involved in normal G2/M phase transition of the mitotic cell cycle. In association with RAD53, also involved in checkpoint control in response to DNA damage.[6]

Publication Abstract from PubMed
Combinatorial library screens based on binding affinity may preferentially select ligands with ability for ionic interactions and miss the biologically relevant ligands that bind more weakly with predominantly hydrophobic interactions.
