Is predicted to encode a protein with the following domains: Heat shock chaperonin-binding; UBA-like superfamily; STI1 domain; Ubiquitin-like domain; Ubiquitin family; and Ubiquitin-like domain superfamily. Is an ortholog of C. elegans ubql-1. In C. elegans, ubql-1 is involved in ERAD pathway; negative regulation of double-strand break repair via homologous recombination; and protein export from nucleus.
