title: Orphan nuclear hormone receptor NR4A1 interacts with HPV16 E2 regulatory protein.
abstract: The human NR4A1 orphan receptor is a member of the TR3 steroid receptor superfamily, which binds DNA at the NBRE and NurRE responsive elements. The TR3 receptors are involved in the regulation of differentiation, proliferation and apoptosis. We report that NR4A1 interacts with human papillomavirus type 16 (HPV16) E2 protein--a key papillomavirus regulatory factor. This interaction might be involved in the transcription regulation of the HPV16 genes and the regulation of infected cell homeostasis.
