Predicted to enable calcium ion binding activity; nucleoside-diphosphatase activity; and protein homodimerization activity. Predicted to be involved in positive regulation of I-kappaB kinase/NF-kappaB signaling and proteoglycan biosynthetic process. Located in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in Desbuquois dysplasia and multiple epiphyseal dysplasia 7. Orthologous to human CANT1 (calcium activated nucleotidase 1).
