Predicted to enable several functions, including GTP binding activity; GTPase activity; and protein homodimerization activity. Predicted to be involved in cobalamin metabolic process. Predicted to be located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; lung; and trophectoderm. Human ortholog(s) of this gene implicated in methylmalonic acidemia cblA type. Orthologous to human MMAA (metabolism of cobalamin associated A). [provided by Alliance of Genome Resources, Apr 2022]
