HRI (heme-regulated inhibitor kinase) phosphorylates the alpha subunit of eIF2alpha kinase, which plays an important role in translational regulation during heme deficiency.
HRI is activated in response to a number of environmental conditions, including heme deficiency, heat shock, and oxidative stress.
Autophosphorylation is essential for the activation of HRI, which causes an arrest of initiation of protein synthesis.
Both HSP 90 and HSC 70 are necessary for all stress-induced HRI activation.
Furthermore, HSC 70 is required for the folding and transformation of HRI into an active kinase and is subsequently required to negatively attenuate the activation of transformed HRI.
Both the N-terminus and the kinase insertion domain, which are unique to HRI, are involved in the heme binding and the heme regulation of HRI.
The human HRI gene maps to chromosome 7p22.1 and encodes a 630aa protein expressed mainly in erythroid cells.
