Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables histone ubiquitin ligase activity. Involved in several processes, including heterochromatin formation; meiotic nuclear division; and retrotransposon silencing. Acts upstream of or within male meiosis I and ubiquitin-dependent protein catabolic process. Part of chromatin and ubiquitin ligase complex. Is expressed in several structures, including alimentary system; endocrine gland; eye; genitourinary system; and trachea. Orthologous to human UBR2 (ubiquitin protein ligase E3 component n-recognin 2).
