Predicted to enable phospholipase A2 activator activity and ubiquitin binding activity. Predicted to be involved in several processes, including negative regulation of protein K63-linked ubiquitination; positive regulation of dendrite extension; and ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within inflammatory response. Predicted to be located in extracellular exosome and synapse. Predicted to be active in cytoplasm and nucleus. Orthologous to human PLAA (phospholipase A2 activating protein). [provided by Alliance of Genome Resources, Apr 2022]
