A cytoplasmic protein complex that contains integrin, mobilferrin and a flavin monooxygenase, is capable of reducing Fe(III) to Fe(II) utilizing NADPH, and is involved in iron transport. Fe(II) is required in the cell as the substrate for ferrochelatase in the synthesis of heme. [ GOC:mah GOC:rph http://www.ncbi.nlm.nih.gov/pubmed/11842004 http://www.ncbi.nlm.nih.gov/pubmed/8639593 ]
