Description

Introduction to PRKAA1 and Its Biological Relevance

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.

Target Background

Function
The catalytic subunit of AMP-activated protein kinase (AMPK) is an energy sensor protein kinase that plays a crucial role in regulating cellular energy metabolism. AMPK responds to reductions in intracellular ATP levels by activating energy-producing pathways and inhibiting energy-consuming processes. This includes inhibiting protein, carbohydrate, and lipid biosynthesis, as well as cell growth and proliferation. AMPK exerts its effects through direct phosphorylation of metabolic enzymes and by longer-term effects via phosphorylation of transcription regulators. It also acts as a regulator of cellular polarity by remodeling the actin cytoskeleton, likely through indirect activation of myosin. AMPK regulates lipid synthesis by phosphorylating and inactivating lipid metabolic enzymes such as ACACA, ACACB, GYS1, HMGCR, and LIPE. It regulates fatty acid and cholesterol synthesis by phosphorylating acetyl-CoA carboxylase (ACACA and ACACB) and hormone-sensitive lipase (LIPE) enzymes, respectively. AMPK regulates insulin signaling and glycolysis by phosphorylating IRS1, PFKFB2, and PFKFB3. AMPK stimulates glucose uptake in muscle by increasing the translocation of the glucose transporter SLC2A4/GLUT4 to the plasma membrane, potentially through mediating phosphorylation of TBC1D4/AS160. AMPK regulates transcription and chromatin structure by phosphorylating transcription regulators involved in energy metabolism, such as CRTC2/TORC2, FOXO3, histone H2B, HDAC5, MEF2C, MLXIPL/ChREBP, EP300, HNF4A, p53/TP53, SREBF1, SREBF2, and PPARGC1A. AMPK serves as a key regulator of glucose homeostasis in the liver by phosphorylating CRTC2/TORC2, leading to CRTC2/TORC2 sequestration in the cytoplasm. In response to stress, AMPK phosphorylates 'Ser-36' of histone H2B (H2BS36ph), promoting transcription. AMPK acts as a key regulator of cell growth and proliferation by phosphorylating TSC2, RPTOR, and ATG1/ULK1. In response to nutrient limitation, AMPK negatively regulates the mTORC1 complex by phosphorylating RPTOR, a component of the mTORC1 complex, and by phosphorylating and activating TSC2. In response to nutrient limitation, AMPK promotes autophagy by phosphorylating and activating ATG1/ULK1, which also activates WDR45. In response to nutrient limitation, AMPK phosphorylates transcription factor FOXO3, promoting FOXO3 mitochondrial import. AMPK also acts as a regulator of circadian rhythm by mediating phosphorylation of CRY1, destabilizing it. AMPK may regulate the Wnt signaling pathway by phosphorylating CTNNB1, leading to its stabilization. AMPK also exhibits tau-protein kinase activity: in response to amyloid beta A4 protein (APP) exposure, AMPK is activated by CAMKK2, leading to phosphorylation of MAPT/TAU. However, the relevance of this finding remains unclear in vivo. AMPK also phosphorylates CFTR, EEF2K, KLC1, NOS3, and SLC12A1.
