I do not think they are "normally" phophorylated. But during in vitro
phosphorylation experiments basically every protein around that has
serine, threonine or tyrosine gets phosphorylated. So much for "kinase
specificity". It's obvious that in non physiological conditions (ie.
kinase assay on IPs) the specificity goes down the drain
