1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. (heat-mediated/Sodium citrate pH 6).
FunctionComponent of some SCF (SKP1-cullin-F-box) protein ligase complex that plays a central role in iron homeostasis by promoting the ubiquitination and subsequent degradation of IREB2/IRP2. Upon high iron and oxygen level, it specifically recognizes and binds IREB2/IRP2, promoting its ubiquitination and degradation by the proteasome. Promotes ubiquitination and subsequent degradation of DCTN1/p150-glued.
PathwayProtein modification; protein ubiquitination.
DomainThe hemerythrin-like region acts as an oxygen and iron sensor by binding oxygen through a diiron metal-center. In absence of oxygen and iron, the protein is ubiquitinated and degraded.
Post-translational modificationsUbiquitinated upon iron and oxygen depletion, leading to its degradation by the proteasome. Ubiquitination is regulated by the hemerythrin-like region that acts as an oxygen and iron sensor.
