The PLAA gene encodes the phospholipase A2 activating protein (PLAA), a ubiquitously expressed protein that plays a critical role in cellular signaling and lipid metabolism. PLAA functions as a co-activator for group IV cytosolic phospholipase A2 (cPLA2), which releases arachidonic acid from membrane phospholipids - the rate-limiting step in eicosanoid biosynthesis.
Beyond its role in lipid signaling, PLAA is involved in protein ubiquitination and degradation through its association with the proteasome regulatory particle. PLAA contains a PFU (PLAA family ubiquitin-binding) domain that allows it to interact with ubiquitin-modified proteins. This function connects PLAA to the ubiquitin-proteasome system (UPS), which is crucial for clearing misfolded and aggregated proteins that accumulate in neurodegenerative diseases.
PLAA has been implicated in Alzheimer's disease pathogenesis through its effects on amyloid-beta production and neuroinflammation. The protein also plays roles in ER stress response and autophagy, both of which are pathways commonly dysregulated in neurodegenerative conditions.
