Predicted to enable identical protein binding activity. Acts upstream of or within erythrocyte differentiation; mitochondrial transport; and regulation of heme biosynthetic process. Located in mitochondrial inner membrane. Is expressed in several structures, including central nervous system; salivary gland; sensory organ; skeletal muscle; and thymus primordium. Orthologous to several human genes including TMEM14C (transmembrane protein 14C). [provided by Alliance of Genome Resources, Apr 2022]
