Predicted to enable EP4 subtype prostaglandin E2 receptor binding activity and ubiquitin ligase-substrate adaptor activity. Predicted to be involved in regulation of inflammatory response; regulation of ubiquitin-protein transferase activity; and ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Predicted to act upstream of or within negative regulation of MAP kinase activity. Predicted to be part of Cul2-RING ubiquitin ligase complex. Predicted to be active in mitochondrion. Orthologous to human FEM1A (fem-1 homolog A). [provided by Alliance of Genome Resources, Apr 2022]
