Enables calcium ion binding activity and identical protein binding activity. Predicted to be involved in positive regulation of I-kappaB kinase/NF-kappaB signaling. Predicted to be located in neuron projection. Predicted to be active in nucleus and perinuclear region of cytoplasm. Is expressed in several structures, including central nervous system; embryo mesenchyme; extraembryonic component; heart; and hemolymphoid system. Orthologous to human S100A4 (S100 calcium binding protein A4). [provided by Alliance of Genome Resources, Apr 2022]
