Specifications
Host Species:
Rabbit
Species Reactivity:
Human, Mouse
Homology:
Predicted species reactivity based on immunogen sequence: Rat: (100%), Chicken: (87%)
Immunogen:
LKB1 antibody was raised against a 15 amino acid synthetic peptide from near the carboxy terminus of human LKB1.
The immunogen is located within amino acids 310 - 360 of LKB1.
Conjugate:
Unconjugated
Tested Applications:
ELISA, WB
Application Note:
LKB1 antibody can be used for detection of LKB1 by Western blot at 1 μg/mL. LKB1 often migrates at a higher than expected molecular weight in SDS-PAGE.

Background:
LKB1 Antibody: The LKB1 serine/threonine protein kinase was initially identified as a tumor suppressor gene mutated in human Peutz-Jeghers syndrome (PJS), a condition resulting in the growth of numerous intestinal polyps classed as hamartomas. LKB1 exists as a heterotrimeric complex with two other proteins, Ste20-related adaptor protein (STRAD) and MO25. Together, this complex can phsophorylate and activate the AMP-activate protein kinase (AMPK). Following AMPK activation by LKB1, AMPK then phosphorylates TSC1 and TSC2, key components of the metabolism-regulating TOR signaling pathway, which antagonizes the activation for the TOR pathway. LKB1 has also been shown to play a fundamental role in controlling the spatial orientation of structures required to maintain an ordered, polarized epithelium.
