Is predicted to encode a protein with the following domains: Ubiquitin-like domain superfamily; Ubiquitin domain; Ubiquitin family; and Ubiquitin-like domain. Is an ortholog of C. elegans ned-8. In C. elegans, ned-8 is involved in negative regulation of DNA damage response, signal transduction by p53 class mediator; negative regulation of gene expression; and regulation of apoptotic process.
