Predicted to enable several functions, including ATPase binding activity; S100 protein binding activity; and protein homodimerization activity. Predicted to be involved in several processes, including positive regulation of nitric-oxide synthase activity; positive regulation of sprouting angiogenesis; and positive regulation of voltage-gated calcium channel activity. Located in sarcoplasmic reticulum. Is expressed in several structures, including brain; heart; inner ear; musculature; and yolk sac. Orthologous to human S100A1 (S100 calcium binding protein A1).
