Most studies on heme regulation have been done in erythroid cells or hepatocytes; however, much less is known about heme metabolism in other cell types. The feline leukemia virus subgroup C receptor (FLVCR) is a 12-transmembrane domain surface protein that exports heme from cells, and it was shown to be required for erythroid development. In this article, we show that deletion of Flvcr in murine hematopoietic precursors caused a complete block in \u03b1\u03b2 T cell development at the CD4+CD8+ double-positive stage, although other lymphoid lineages were not affected. Moreover, FLVCR was required for the proliferation and survival of peripheral CD4+ and CD8+ T cells. These studies identify a novel and unexpected role for FLVCR, a major facilitator superfamily metabolite transporter, in T cell development and suggest that heme metabolism is particularly important in the T lineage.<\/jats:p>","DOI":"10.4049\/jimmunol.1402172","type":"journal-article","created":{"date-parts":[[2015,1,13]],"date-time":"2015-01-13T05:28:26Z","timestamp":1421126906000},"page":"1677-1685","source":"Crossref","is-referenced-by-count":36,"title":["Heme Exporter FLVCR Is Required for T Cell Development and Peripheral Survival"],"prefix":"10.1093","volume":"194","author":[{"given":"Mary","family":"Philip","sequence":"first","affiliation":[{"name":"Division of Hematology, University of Washington , Seattle, WA 98195"},{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center , Seattle, WA 98109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott A","family":"Funkhouser","sequence":"additional","affiliation":[{"name":"Division of Hematology, University of Washington , Seattle, WA 98195"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edison Y","family":"Chiu","sequence":"additional","affiliation":[{"name":"Division of Hematology, University of Washington , Seattle, WA 98195"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan R","family":"Phelps","sequence":"additional","affiliation":[{"name":"Division of Hematology, University of Washington , Seattle, WA 98195"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey J","family":"Delrow","sequence":"additional","affiliation":[{"name":"Genomics Shared Resource, Fred Hutchinson Cancer Research Center , Seattle, WA 98109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Cox","sequence":"additional","affiliation":[{"name":"University of Utah Metabolomics Core Facility , Salt Lake City, UT 84132"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pamela J","family":"Fink","sequence":"additional","affiliation":[{"name":"Department of Immunology, University of Washington , Seattle, WA 98109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janis L","family":"Abkowitz","sequence":"additional","affiliation":[{"name":"Division of Hematology, University of Washington , Seattle, WA 98195"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,2,15]]},"reference":[{"key":"2025030705070128200_r1","doi-asserted-by":"crossref","first-page":"1604","DOI":"10.1016\/j.bbamcr.2012.04.008","article-title":"Structure, function, and assembly of heme centers in mitochondrial respiratory complexes","volume":"1823","author":"Kim","year":"2012","journal-title":"Biochim.
