Predicted to enable guanidinoacetate N-methyltransferase activity and identical protein binding activity. Acts upstream of or within several processes, including creatine biosynthetic process; regulation of growth; and spermatogenesis. Predicted to be located in cytosol. Predicted to be active in cytoplasm and nucleus. Is expressed in pancreas. Used to study guanidinoacetate methyltransferase deficiency. Human ortholog(s) of this gene implicated in amino acid metabolic disorder and guanidinoacetate methyltransferase deficiency. Orthologous to human GAMT (guanidinoacetate N-methyltransferase).
