Activating Compound

EC Number Activating Compound Comment Organism Structure
3.1.1.4 additional information activity of the GVIA PLA2 may be regulated through many different mechanisms, including ATP binding, caspase cleavage, calmodulin, and possible ankyrin repeat mediated protein aggregation Homo sapiens

Application

EC Number Application Comment Organism
3.1.1.4 drug development with the classification of GVIIA PLA2 as a positive risk factor in coronary heart disease, it has become a very attractive drug target. Recent clinical trials with GVIIA PLA2 inhibitor have shown a decrease in the complex atherosclerotic lesions that lead to unstable lesions, as well as other cardiovascular disease markers Homo sapiens

Inhibitors

EC Number Inhibitors Comment Organism Structure
3.1.1.4 bromoenollactone is not specific for GVIA PLA2 and actually functions through activation of the inhibitor by GVIA PLA2 followed by nonspecific covalent modification of cysteine residues in all proximally located enzymes Homo sapiens

General Information

EC Number General Information Comment Organism
3.1.1.4 malfunction absence of the GIVA PLA2 gene significantly reduces the effects of many inflammatory disease Mus musculus
3.1.1.4 malfunction patient with defects in GIVA PLA2 shows decreases in PLA2 activity, eicosanoid biosynthesis, and the generation of many small intestinal ulcers Homo sapiens
3.1.1.4 physiological function GIIA PLA2 is a potent antimicrobial agent. Role of the GVIA PLA2 in different signaling pathways. GVIIA PLA2 has anti-inflammatory activity in vivo, is a positive risk factor in coronary heart disease Homo sapiens
3.1.1.4 physiological function GVIA PLA2 plays an important role in bone formation, apoptosis, insulin secretion, and sperm development. GVIA PLA2 in combination with the GIVA PLA2 play an important role in Wallerian degeneration and axon regeneration in nerve injury. GIVA PLA2 is generally considered to be a central enzyme mediating generation of eicosanoids and hence many inflammatory processes Mus musculus
