一般說明
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, a.a. 2-431, with N-terminal GST-tag).
應用
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
生化／生理作用
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.
