Target intelligence / Profile preview
AMP-activated protein kinase beta subunit 1 (PRKAB1)
- Target
- PRKAB1
- Molecular classification
- Enzyme, Regulatory subunit
01
Overview
PRKAB1 encodes the 5'-AMP-activated protein kinase subunit beta-1, a regulatory component of the AMPK complex. AMPK functions as a central energy sensor, responding to metabolic stresses. PRKAB1 acts as a positive regulator, essential for sensing changes in cellular energy levels and regulating glucose uptake, lipid metabolism, and mitochondrial biogenesis. Its dysregulation is implicated in metabolic disorders such as obesity, type II diabetes mellitus, cardiovascular diseases, and potentially cancer.
