An N-myristoylated cell-permeable PI 3-K p110 beta-derived G beta-gamma-binding peptide (aa514-537 in p110 beta C2-helical linker region) that prevents G beta-gamma-, but not RTK-, mediated p100 beta activation both in cell-free assays (1uM) and in cultures (30uM in p110 beta/p85/Akt/G beta-gamma-transfected HEK 293E cells) without affecting basal p100 beta activity, p110 beta-Rab5 interaction, nor G beta-gamma-dependent activation of adenylyl cyclase or p101-p110-gamma dimer. The ATP-competitive p110 beta inhibitior TGX-221 can be used in conjunction for studying G beta-gamma dependency of p110 beta-mediated cellular functions.
Storage and Stability:May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
