Predicted to be involved in mitochondrial proton-transporting ATP synthase complex assembly. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; nasal cavity epithelium; orbito-sphenoid; and urinary system. Human ortholog(s) of this gene implicated in mitochondrial complex V (ATP synthase) deficiency nuclear type 2. Orthologous to human TMEM70 (transmembrane protein 70).
