Predicted to enable heme binding activity and heme transmembrane transporter activity. Predicted to be involved in heme export. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Is expressed in several structures, including central nervous system and yolk sac. Used to study proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome. Human ortholog(s) of this gene implicated in proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome. Orthologous to human FLVCR2 (FLVCR heme transporter 2). [provided by Alliance of Genome Resources, Apr 2022]
