Complex of human LKB1, also known as STK11 (GenBank Accession No. NM_000455, a.a. 2-433, with N-terminal His-tag), MO25 (GenBank Accession No. NM_016289, a.a. 2-341, with N-terminal GST-tag), and STRAD (GenBank Accession No. NM_001003787, a.a. 2-431, with N-terminal GST-tag). Calculated MW=49 kDa* (LKB1), 66 kDa (MO25), and 74 kDa (STRAD), expressed in Sf9 cells using a Baculovirus expression system. *LKB1 runs anomalously on SDS-PAGE.
45 mM Tris-HCl, pH 8.0, 124 mM NaCl, 2.4 mM KCl, 18 mM glutathione, 3 mM DTT, 10% glycerol
Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
100 uM ATP and 0.2 mg/ml LKBtide peptide was used as a substrate. Reaction was incubated at 30°C for 30 min. Reaction progress was monitored using ADP-Glo reagents (Promega).
