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.
