Lpl Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Lipoprotein Lipase (LPL) is a member of the lipase family with a classic α/β hydrolase fold. Key structural features include: [@neuroinflammation2015]
N-terminal domain (residues 1-313): Contains the catalytic triad (Ser132, Asp156, His241) and lid region
C-terminal domain (residues 314-475): Involved in lipid binding and interactions with GPIHBP1
Lid region: Flexible loop covering the active site, undergoes conformational change upon substrate binding
Heparin-binding domain: Positively charged region for attachment to endothelial heparan sulfate
The functional enzyme is a homodimer, with each monomer containing a catalytic site [1]. [@cellular2018]
Normal Function
LPL catalyzes the hydrolysis of triglycerides in chylomicrons and VLDL: [@therapeutic2017]
Lipolysis: Cleaves fatty acids from triglyceride core → free fatty acids for tissue uptake
Fatty acid uptake: Released fatty acids enter cells for oxidation or storage
Remnant uptake: Smaller remnant particles are cleared by liver
