p38 mitogen-activated protein kinases (MAPKs) play important roles in various
cellular stress responses, including cell death, which is roughly categorized
into apoptosis and necrosis. Although p38 signaling has been extensively studied,
the molecular mechanisms of p38-mediated cell death are unclear. ASK1 is a
stress-responsive MAP3K that acts as an upstream kinase of p38 and is activated
by various stresses, such as oxidative stress. Here, we show that NR4A2, a member
of the NR4A nuclear receptor family, acts as a necrosis promoter downstream of
ASK1-p38 pathway during oxidative stress. Although NR4A2 is well known as a
nucleus-localized transcription factor, we found that it is translocated into the
cytosol after phosphorylation by p38. Because the phosphorylation site mutants of
NR4A2 cannot rescue the cell death-promoting activity, ASK1-p38 pathway-dependent
phosphorylation and subsequent cytoplasmic translocation of NR4A2 may be required
for oxidative stress-induced cell death. In addition, NR4A2-mediated cell death
does not depend on caspases and receptor-interacting protein 1 (RIP1)-RIP3
complex, suggesting that NR4A2 promotes an RIP kinase-independent necrotic type
of cell death. Our findings may enable a more precise understanding of molecular
mechanisms that regulate oxidative stress-induced and p38-mediated necrosis.
