Phosphorylated CHKtide

Phosphorylated CHKtide is a synthetic peptide substrate derived from CDC25C, which is phosphorylated by CHK1/CHK2 in one of the DNA repair pathways. Phosphorylated CHKtide is used in the assays of cell cycle checkpoint kinases 1 and 2 (CHK1/CHK2) and salt-inducible kinases (SIKs) [1].
