Expression of Pirh2, a Newly Identified Ubiquitin Protein Ligase, in Lung Cancer

Abstract excerpt

Maintenance of p53 function is important for normal cell growth and development, and loss of p53 function contributes directly to malignant tumor development. The recently discovered Pirh2 protein is an ubiquitin-protein ligase that negatively regulates p53 through activity by targeting it for degradation. To determine how Pirh2 may mediate lung tumorigenesis, we evaluated Pirh2 expression in human and mouse lung...
