Human Iron−Sulfur Cluster Assembly, Cellular Iron Homeostasis, and Disease†
Iron-sulfur (Fe-S) proteins contain prosthetic groups consisting of two or more iron atoms bridged by sulfur ligands, which facilitate multiple functions, including redox activity, enzymatic function, and maintenance of structural integrity. More than 20 proteins are involved in the biosynthesis of iron-sulfur clusters in eukaryotes. Defective Fe-S cluster synthesis not only affects activities ...
متن کاملHuman ISD11 is essential for both iron-sulfur cluster assembly and maintenance of normal cellular iron homeostasis.
The LYR family consists of proteins of diverse functions that contain the conserved tripeptide 'LYR' near the N-terminus, and it includes Isd11, which was previously observed to have an important role in iron-sulfur (Fe-S) cluster biogenesis in Saccharomyces cerevisiae. Here, we have cloned and characterized human ISD11 and shown that human ISD11 forms a stable complex in vivo with the human cy...
متن کاملIron and Neurodegeneration: From Cellular Homeostasis to Disease
Accumulation of iron (Fe) is often detected in the brains of people suffering from neurodegenerative diseases. High Fe concentrations have been consistently observed in Parkinson's, Alzheimer's, and Huntington's diseases; however, it is not clear whether this Fe contributes to the progression of these diseases. Other conditions, such as Friedreich's ataxia or neuroferritinopathy are associated ...
متن کاملIron-sulfur cluster biogenesis and human disease.
Iron-sulfur (Fe-S) clusters are essential for numerous biological processes, including mitochondrial respiratory chain activity and various other enzymatic and regulatory functions. Human Fe-S cluster assembly proteins are frequently encoded by single genes, and inherited defects in some of these genes cause disease. Recently, the spectrum of diseases attributable to abnormal Fe-S cluster bioge...
متن کاملEffects of Environmental Pollutants on Cellular Iron Homeostasis and Ultimate Links to Human Disease
Chronic disease has increased in the past several decades, and environmental pollutants have been implicated. The magnitude and variety of diseases may indicate the malfunctioning of some basic mechanisms underlying human health. Environmental pollutants demonstrate a capability to complex iron through electronegative functional groups containing oxygen, nitrogen, or sulfur. Cellular exposure t...
