 == Function ==
-'''Protein kinase Spk1 (Rad53)''' is a serine/threonine protein kinase which phosphorylates proteins.  Rad53 controls S-phase checkpoint and G1 and G2 DNA damage checkpoints.  Rad53 phosphorylates proteins at serine, threonine and tyrosine residues.

-Rad53 contains phosphothreonine recognition domains: '''FHA1''' at the N-terminal (residues 1-164) which selects for Asp at position +3 relative to phosphothreonine and '''FHA2''' at the C-terminal (residues 573-730) which selects for Ile at position +3 relative to phosphothreonine. Two '''SCD''' - SQ/TQ-rich cluster domains – are flanking the '''kinase''' domain.
+Rad53 contains phosphothreonine (PTO) recognition domains: '''FHA1''' at the N-terminal (residues 1-164) which selects for Asp at position +3 relative to PTO and '''FHA2''' at the C-terminal (residues 573-730) which selects for Ile at position +3 relative to PTO. Two '''SCD''' - SQ/TQ-rich cluster domains – are flanking the '''kinase''' domain. SCD domain is associated with DNA-damage-response proteins.
