Predicted to enable enzyme binding activity; heme binding activity; and protein homodimerization activity. Acts upstream of or within several processes, including cellular calcium ion homeostasis; endoplasmic reticulum unfolded protein response; and regulation of store-operated calcium entry. Located in Golgi apparatus and endoplasmic reticulum. Is expressed in several structures, including embryo mesenchyme; genitourinary system; gut; olfactory epithelium; and vertebral axis musculature. Orthologous to human STC2 (stanniocalcin 2). [provided by Alliance of Genome Resources, Apr 2022]
