Predicted to enable several functions, including WW domain binding activity; enzyme binding activity; and tumor necrosis factor receptor binding activity. Predicted to be involved in positive regulation of JNK cascade; positive regulation of protein kinase activity; and regulation of I-kappaB kinase/NF-kappaB signaling. Predicted to act upstream of or within respiratory gaseous exchange by respiratory system and respiratory tube development. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Orthologous to human TRAF4 (TNF receptor associated factor 4). [provided by Alliance of Genome Resources, Apr 2022]
