Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables protein tag activity. Involved in several processes, including ISG15-protein conjugation; defense response to other organism; and positive regulation of erythrocyte differentiation. Acts upstream of or within modification-dependent protein catabolic process and response to bacterium. Predicted to be located in extracellular region. Predicted to be active in cytoplasm and nucleus. Is expressed in brain; decidua; embryo; labyrinthine zone; and mesometrium. Human ortholog(s) of this gene implicated in immunodeficiency 38. Orthologous to human ISG15 (ISG15 ubiquitin like modifier).
