Predicted to enable protein homodimerization activity and transcription coactivator activity. Involved in defense response to other organism; negative regulation of viral entry into host cell; and negative regulation of viral transcription. Acts upstream of or within positive regulation of protein localization to nucleus and stem cell population maintenance. Located in cytosol and nucleus. Is expressed in cerebellum layer; female reproductive system; and urinary system. Orthologous to human TRIM8 (tripartite motif containing 8). [provided by Alliance of Genome Resources, Apr 2022]
