🧬 Gene Info
Gene SymbolPLIN2
Chromosome9p22.1
Protein TypeStructural Protein
Target ClassStructural Protein
FunctionLipid Storage: Promotes triglyceride storage by facilitating lipid droplet formation and preventing lipolysis [@brasaemle2004]
Mechanism of ActionDirect PLIN2 inhibitors would reduce lipid droplet formation and stability, promoting lipid mobilization and reducing pathological lipid accumulation. Indirect approaches target upstream regulators of PLIN2 expression or modulate associated lipases to alter lipid storage dynamics in metabolic and neurodegenerative disease states.
