PRKAA1 (Protein Kinase, AMP-Activated, alpha 1 Catalytic Subunit) is a serine/threonine kinase that regulates cellular energy metabolism by responding to AMP/ATP ratios. It plays critical roles in:
Cancer: Promoting proliferation and inhibiting apoptosis via JNK1 and Akt pathways in gastric cancer cells .
Autophagy: Mediating mitochondrial clearance (mitophagy) in erythrocyte development .
Immunology: Modulating B-cell responses and antibody production .
Vascular Health: Regulating glycolysis in endothelial cells exposed to disturbed flow, impacting atherosclerosis .
The FITC-conjugated antibody is used to visualize PRKAA1 localization and activity in these contexts.
Use Case: Quantifying PRKAA1 expression in cell populations.
Example: Boster’s Picoband antibody (A00994-6) was validated in SiHa cells, demonstrating strong FITC signals for intracellular staining .
Protocol: Fixation with 4% paraformaldehyde, permeabilization, blocking with goat serum, and detection with DyLight®488-conjugated secondary antibodies .
Use Case: Localizing PRKAA1 in subcellular compartments (e.g., mitochondria, cytoplasm).
Example: Antibodies from Cusabio (CSB-PA618759LC01HU) and Antibodies-Online (ABIN3021788) are validated for IF, enabling visualization in human, mouse, and rat cells .
Use Case: Confirming protein expression levels.
Example: The unconjugated version of the antibody is often used for WB, but FITC-conjugated variants may require alternative detection methods (e.g., compatible secondary antibodies) .

Flow Cytometry: Boster’s A00994-6 showed distinct FITC signals in SiHa cells, distinguishing between isotype controls and targeted populations .
IF: Cusabio’s antibody demonstrated specificity in detecting PRKAA1 localization in human endothelial cells, aligning with its role in glycolysis regulation .
Gastric Cancer: PRKAA1 overexpression promotes proliferation and inhibits apoptosis via JNK1 and Akt activation. FITC-conjugated antibodies could track PRKAA1 dynamics in real-time imaging studies .
Endothelial Cells: PRKAA1-driven glycolysis protects against atherosclerosis. FITC-labeled antibodies may visualize PRKAA1 upregulation in disturbed flow conditions .
PRKAA1 phosphorylates ULK1 at Ser555, initiating mitophagy. FITC-conjugated antibodies could monitor ULK1 complex formation in reticulocytes .
B-Cell Function: AMPKα1 dampens primary antibody responses but enhances recall immunity. FITC-conjugated antibodies might trace AMPKα1 activity in plasma cells during vaccination studies .
