Acts upstream of or within negative regulation of canonical Wnt signaling pathway; negative regulation of epithelial to mesenchymal transition; and protein dephosphorylation. Located in mitochondrion. Is expressed in several structures, including early conceptus and oocyte. Human ortholog(s) of this gene implicated in paraganglioma. Orthologous to human SDHAF2 (succinate dehydrogenase complex assembly factor 2). [provided by Alliance of Genome Resources, Apr 2022]
