Low affinity heme transporter involved in the assimilation of exogenous heme during conditions of low cellular iron. Induced in iron-deplete conditions (at protein level) (PubMed:29549126, PubMed:12888492). Repressed in iron-replete conditions by transcriptional repressor fep1 (PubMed:29549126, PubMed:12888492). Impairs heme import into cell; simultaneous disruption of shu1 exacerbates the effect. Belongs to the major facilitator superfamily.
