Notes: Malantide is a synthetic peptide derived from the β-subunit of human phosphorylase kinase and is a fluorescent substrate for PKA and PKC.{72271,72272} Upon phosphorylation by PKA or PKC, the intrinsic tyrosine fluorescence decreases and can be used to quantify PKA and PKC activity. Malantide displays an emission at 302 nm upon excitation at 285 nm.
