Predicted to enable protein serine/threonine kinase activator activity. Predicted to be involved in calcium ion homeostasis; odontogenesis; and positive regulation of protein phosphorylation. Predicted to act upstream of or within response to bacterium. Predicted to be located in endoplasmic reticulum and extracellular space. Predicted to colocalize with Golgi apparatus. Human ortholog(s) of this gene implicated in amelogenesis imperfecta type 1G. Orthologous to human FAM20A (FAM20A golgi associated secretory pathway pseudokinase).
