Iron-sulfur (Fe-S) clusters are required for the functions of mitochondrial aconitase, mammalian iron regulatory protein 1, and many other proteins in multiple subcellular compartments. Mitochondrial and cytosolic isoforms of the human Fe-S cluster scaffold protein, iron-sulfur cluster assembly enzyme (ISCU), is involved in activation of iron uptake, redistribution of intracellular iron, and decreased utilization of iron in Fe-S proteins.
Defects in ISCU gene are the cause of myopathy with exercise intolerance Swedish type (MEIS), which is characterized by lifelong severe exercise intolerance (PMID: 18304497). Two ISCU isoforms ISCU1 (cytosolic, 15 kDa) and ISCU2 (mitochondrial, 18 kDa), were produced by alternative splicing, and ISCU2 is considered the canonical isoform1. ISCU2 protein is rapidly processed upon maturation (PMID: 11060020). Proteintech’s ISCU antibody 14812-1-AP is raised against the full-length ISCU2 and is expected to detect 14 kDa,15 kDa and 18-19 kDa bands which has been reported in the previous observation (PMID: 11060020).
