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.
Applications:
Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
