Abstract
  • Erk8 (MAPK15) is a large MAP kinase already implicated in the regulation of the functions of different nuclear receptors and in cellular proliferation and transformation. Here, we identify ERR? as a novel Erk8-interacting protein. As a consequence of such interaction, Erk8 induces Crm1-dependent translocation of ERR? to the cytoplasm and inhibits its transcriptional activity. Also, we identify in Erk8 two LXXLL motifs, typical of agonist-bound nuclear receptor corepressors, as necessary features for this MAP kinase to interact with ERR? and to regulate its cellular localization and transcriptional activity. Ultimately, based on the well-established positive role of ERR? in mammary carcinogenesis, we demonstrate that Erk8 is able to counteract, in immortalized human mammary cells, ERR? activation induced by the EGF receptor pathway, often deregulated in breast cancer. Altogether, these results reveal a novel function for Erk8 as a bona fide ERR? corepressor, involved in the control of its cellular localization by nuclear exclusion, and suggest a key role for this MAP kinase in the biological activities of this nuclear receptor.
