Enables phospholipase A2 activity. Predicted to be involved in several processes, including cholesterol homeostasis; glycerophospholipid metabolic process; and positive regulation of lipid localization. Predicted to act upstream of or within several processes, including cellular response to leukemia inhibitory factor; erythrocyte maturation; and negative regulation of cytokine production involved in inflammatory response. Predicted to be located in acrosomal vesicle and extracellular space. Orthologous to human PLA2G10 (phospholipase A2 group X). [provided by Alliance of Genome Resources, Apr 2022]
