I study the regulation of a gene called RGMc (also called Hemojuvelin (HJV) in humans). RGMc/HJV plays a critical role in iron metabolism, as inactivating mutations cause juvenile hemochromatosis, a severe iron overload disorder.
The long-range goals of my research are to enhance understanding of the molecular mechanisms by which evolution has shaped the regulation of gene expression in a family of genes, and apply this knowledge to understand select human diseases.
The primary focus of my research is three-fold:
(1) to understand the genomic structure of the Repulsive Guidance Molecule (RGM) family,
(2) to understand the mechanisms of transcriptional regulation of RGMc,
(3) to understand the basics of the molecular evolution of the RGM family.
An interactive Molecular Model of the RGM-family at the protein level
For the Transcriptional Regulation of RGMc, see this 2010 article in Genomics.
