Summary: Predicted to enable heme binding activity and heme transmembrane transporter activity. Acts upstream of or within several processes, including chordate embryonic development; embryonic digit morphogenesis; and hematopoietic or lymphoid organ development. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Predicted to be active in mitochondrion. Is expressed in ectoplacental cone; immune system; liver; placenta; and yolk sac. Used to study Diamond-Blackfan anemia. Orthologous to human FLVCR1 (FLVCR heme transporter 1).

Endothelial cells require functional FLVCR1a during developmental and adult angiogenesis.
Title: Endothelial cells require functional FLVCR1a during developmental and adult angiogenesis.
study found that primary and immortalized murine macrophages downregulate Flvcr mRNA levels upon LPS stimulation; findings point to a new role for FLVCR and heme export in macrophages responses to infection and inflammation
Title: TLR Stimulation Dynamically Regulates Heme and Iron Export Gene Expression in Macrophages.
Data shows that FLVCR1a participates in the control of intestinal mucosa homeostasis by exporting the excess of de novo synthesized heme from intestinal cells.
Title: Crucial Role of FLVCR1a in the Maintenance of Intestinal Heme Homeostasis.
These studies identify a novel and unexpected role for FLVCR, a major facilitator superfamily metabolite transporter, in T cell development
Title: Heme exporter FLVCR is required for T cell development and peripheral survival.
Flvcr1a maintains a free heme pool that regulates heme synthesis and degradation as well as cytochromes P450 expression and activity.
Title: Heme exporter FLVCR1a regulates heme synthesis and degradation and controls activity of cytochromes P450.
FLVCR is redundant in stem cells but has critical and contrasting stage-specific roles in discrete hematopoietic lineages
Title: FLVCR is necessary for erythroid maturation, may contribute to platelet maturation, but is dispensable for normal hematopoietic stem cell function.
Hemochromatosis is associated not only with excessive accumulation of free iron in the retina and retinal pigment epithelium but also with excessive accumulation of heme.
Title: Polarized distribution of heme transporters in retinal pigment epithelium and their regulation in the iron-overload disease hemochromatosis.
data show that FLVCR exports heme & is required by erythroid progenitors to complete terminal differentiation; data show that FLVCR functions in macrophage heme-iron recycling and that systemic iron balance involves heme-iron trafficking via FLVCR
Title: A heme export protein is required for red blood cell differentiation and iron homeostasis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
