Abl substrate peptide is a synthetic peptide which can be used as a substrate for Abl kinase in kinase assays. Abl substrate peptide is phosphorylated by Abl kinase with a Km of 4 µM. Abl (Abelson) kinase is a plasma membrane associated non-receptor tyrosine kinase with transforming activity. The three lysines on the carboxy terminus of Abl substrate peptide allow it to be used in phosphocellulose kinase assays.
