Detection of Human, Mouse, and Rat ARK5/NUAK1 by Western Blot. Western blot shows lysates of Saos‑2 human osteosarcoma cell line, mouse heart tissue, and rat heart tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse/Rat ARK5/NUAK1 Monoclonal Antibody (Catalog # MAB6978) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for ARK5/NUAK1 at approximately 74 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

AMPK-related kinase 5 (ARK5), also known
as NUAK1, is a 74 kDa intracellular Ser/Thr kinase that promotes cell survival
during nutrient deprivation and TNF family ligand-induced apoptosis. ARK5 is
activated by Akt, NDR2, and LKB1-mediated phosphorylation at multiple serine
and threonine residues. It inhibits the activation of Caspase-6, Caspase-8, and
myosin phosphatases but promotes the activation of MMP2 and MMP9. ARK5
overexpression in several cancers contributes to increased tumor progression
and aggressiveness. ARK5 contains one catalytic domain (aa 65-306), and a short
isoform of the human protein is prematurely tuncated within this domain. Within
aa 311-462, human ARK5 shares 88% and 85% aa sequence identity with mouse and
rat ARK5, respectively.
