Descripción general

The product is a complex of human Liver kinase B1 (LKB1), also known as serine/threonine kinase 11 (STK11) (GenBank Accession No. NM_000455; amino acids 2-433, with N-terminal His-tag), mouse protein- 25 (MO25) or calcium binding protein 39 (CAB39) (GenBank Accession No. NM_016289; amino acids 2-341, with N-terminal GST-tag) and STE20-related kinase adaptor alpha (STRAD) (GenBank Accession No. NM_001003787).

Aplicación

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Acciones bioquímicas o fisiológicas

Liver kinase B1 (LKB1), also known as serine/threonine kinase 11 (STK11), is a serine/threonine kinase that regulates cell polarity and functions as a tumor suppressor protein. LKB1 regulates the activity of adenosine monophosphate-activated protein kinase (AMPK), promoting the suppression of growth and proliferation under energetically unfavorable conditions. Mouse protein-25 (MO25) or calcium binding protein 39 (CAB39) is a scaffolding protein which modulates the activities of STE20 family protein kinases. The MO25a isoform is part of the LKB1 tumor suppressor complex. STE20-related kinase adaptor α (STRAD) is a pseudokinase. It forms a heterotrimeric complex with LKB1 and MO25. The LKB1/MO25/STRAD complex modulates the metabolism, proliferation and cellular polarity of human intestinal epithelial cells.

Forma física

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol and 3 mM DTT.

Nota de preparación

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.
