Protocol

Kinase experiment [1]:

In vitro kinase assays

We carried out in vitro kinase assays (except for Cdc28) in the presence of 0.2 μCi /μl [γ-32P]ATP at low ATP concentration (10 nM) so that IC50 values represent a rough measure of the inhibition constant (Ki). Measurement of inhibitor IC50 values were done as Liu, Y. et al. described. Purified Cdc28–His6 (1 nM) and MBP–Clb2 (3 nM) were incubated for 10 min at 23℃ in a 25 μl reaction mixture containing 5 μg histone H1, 1 μCi of [γ-32P]ATP (1 μCi per 10 μM and 1μCi per 1 mM), and varying concentrations of 1-NM-PP1 in kinase buffer (25mM HEPES-NaOH pH 7.4, 10mM NaCl, 10mM MgCl2 and 1mM dithiothreitol). Reaction products were analysed by 15% SDS–PAGE followed by autoradiography. For the determination of Cdc28 kinetic constants, varying concentrations of [γ-32P]ATP (1 μCi per 100 μM) were incubated and analysed as above.

Cell lines

PDK1?/? ES cells

Preparation method

This compound is soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

10 μM for 24h-72h; or 20 μM for 48h

Applications

1-NM-PP1 suppressed the phosphorylation of PDK1 targets in PDK1?/? ES cells expressing PDK1 L159G but not WT PDK1. Moreover, 1-NM-PP1 inhibited sorbitol-induced MSK1 S212 T-loop phosphorylation, ERK/p38MAPK phosphorylation sites S581 and ERK/p38 dependent autophosphorylation at S376. 1-NM-PP1 also inhibited IGF1-stimulated PKB/Akt T308 phosphorylation and S6K activity in PDK1?/? +LG ES cells.

Background

1-NM-PP1 is a C3-modified analog of cell-permeable PP1, acts as a potent and selective inhibitor of protein kinase families [1].

1-NM-PP1 has shown the selective inhibition of protein kinases that have been mutated with the IC50 values of 28 μM, 1.0 μM, 3.4 μM, 29 μM, 24 μM,4.3 nM, 3.2 nM, 120 nM,5 nM and 8 nM for v-Src, c-Fyn, c-Abl, CDK2, CAMKII, v-Src-as1, c-Fyn-as1, cAbl-as2, CDK2-as1 and CAMKII-as1, respectively. 1-NM-PP1 inhibited each of the five target kinases at low nanomolar concentrations with target-specificities ranging from 85-fold to 400-fold measured against the most inhibitable wild-type kinases. In addition, the in vitro study has also revealed that Cdc28-as1 is highly sensitive to 1-NM-PP1 with ATP kinetic Km values of 35 μM and 322 μM, the Kcat values of 132 min-1 and 21.3 min-1, the Kcat/Km values of 3.7 and 0.066, the IC50 values of 22 μM and 0.002 μM for Cdc28/Clb2 and Cdc28-as1/Clb2, respectively [1].
