RRREEETEEE-OH is derived from the kinase II phosphorylation site found in casein and is a specific substrate for casein kinase-2. It is not phosphorylated by casein kinase-1 or other protein kinases such as cAMP-dependent protein kinase, protein kinase G, phosphorylase kinase, myosin light chain kinase, and EGF receptor kinase.
