PITK was previously identified as a novel PP1 targeting subunit implicated in modulating the phosphorylation of the transcriptional regulator heterogeneous nuclear ribonucleoprotein K (hnRNP K). Through the phosphorylation of PITK at S1013 and S1017 (residues that flank or reside within a PP1C-binding motif), the binding of the PP1 catalytic subunit to PITK, and subsequently the activity of the holoenzyme, are discretely controlled.
