Heme allocation in eukaryotic cells relies on mitochondrial heme export through FLVCR1b to cytosolic GAPDH [PDF]
Nature CommunicationsHeme is an iron-containing cofactor generated in mitochondria that must leave this organelle to reach protein targets in other cell compartments. Because mitochondrial heme binding by cytosolic GAPDH enables its distribution in cells, we sought to ...

Hsp90 in Human Diseases: Molecular Mechanisms to Therapeutic Approaches [PDF]
Cells, 2022 The maturation of hemeprotein dictates that they incorporate heme and become active, but knowledge of this essential cellular process remains incomplete. Studies on chaperon Hsp90 has revealed that it drives functional heme maturation of inducible nitric
