siRNA knock down of APT-1 and APT-2 in NRAS and BRAF mutant melanoma(a) and (b) melanoma cells with indicated mutations were transfected with APT-1 or APT-2 targeting siRNA pools (siAPT1, siAPT2) or their combination and compared to cells transfected with a non-targeting siRNA pool (concentration 100nM, incubation 72hrs). a. Immunoblots after APT-1, APT-2 or dual knock down. Densitometry values for APT-1 and APT-2 show the percentage of protein expression following siRNA treatment. No relevant changes in NRAS downstream effectors are seen following APT-1, APT-2 or dual knock down. b. Bar graphs depicting viable cells after APT-1, APT-2 or dual knock down. Analyses revealed no significant differences in cell viability in NRAS and BRAF mutant melanoma cells (incubation 72hrs, n > 3, error bars represent SD)

APT-2 also known as lysophospholipase A2 (lypla2) is an enzyme involved in lipid metabolism. APT-2 has a molecular mass of approximately 25 kDa and is expressed in various tissues including the brain heart and muscle. As an important member of the lipid acyl hydrolase family it removes fatty acids from lysophospholipids. Researchers often use the names anti-APT and anti-ApT in antibody studies targeting this enzyme. APT-2 identification in these tissues highlights its importance in lipid processing and suggests its broader functional implications.
Biological function summary

APT-2 plays a critical role in maintaining phospholipid homeostasis contributing to membrane fluidity and signal transduction. It is involved in hydrolyzing lysophospholipids into lysoglycerophospholipids and free fatty acids. Not part of a complex APT-2 acts as an individual enzyme handling specific substrates in this context. Its activity regulates levels of lipid signaling molecules influencing cellular responses to environmental cues. APT-2 also contributes to energy storage via metabolism of lipid substrates linking its enzymatic activity to broader metabolic pathways.

Pathways

APT-2 holds significance in both metabolic and signaling pathways specifically the glycerophospholipid metabolism and lysophospholipid signaling pathways. It catalyzes reactions key to these pathways and intersects with proteins like phospholipase A2 and PLA2G6. Glycerophospholipid metabolism sees APT-2 breaking down molecules to sustain membrane integrity and cellular communication processes. In lysophospholipid signaling its activity regulates bioactive lipid levels which impact a variety of cellular signaling events showing a well-integrated role in cellular physiology.

The dysfunction of APT-2 links to neurodegenerative diseases and cardiovascular disorders. Altered APT-2 activity is associated with Alzheimer's disease due to disrupted lipid homeostasis and membrane composition. The enzyme's interaction with proteins like phospholipase A2 highlights its involvement in these neurodegenerative processes. Furthermore cardiovascular health implications arise from its role in lysophospholipid metabolism and associated inflammatory responses. Aberrations in APT-2 function can modulate pathways that exacerbate atherosclerosis further connecting its activity to disease states.

Target data

Acts as an acyl-protein thioesterase hydrolyzing fatty acids from S-acylated cysteine residues in proteins such as trimeric G alpha proteins, GSDMD, GAP43, ZDHHC6 or HRAS (PubMed : 21152083, PubMed : 28826475). Deacylates GAP43 (PubMed : 21152083). Mediates depalmitoylation of ZDHHC6 (PubMed : 28826475). Has lysophospholipase activity (PubMed : 25301951). Hydrolyzes prostaglandin glycerol esters (PG-Gs) in the following order prostaglandin D2-glycerol ester (PGD2-G) > prostaglandin E2 glycerol ester (PGE2-G) > prostaglandin F2-alpha-glycerol ester (PGF2-alpha-G) (PubMed : 25301951). Hydrolyzes 1-arachidonoylglycerol but not 2-arachidonoylglycerol or arachidonoylethanolamide (PubMed : 25301951).
