Predicted to enable several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; identical protein binding activity; and ubiquitin-like protein ligase binding activity. Predicted to be involved in several processes, including defense response to other organism; negative regulation of type I interferon-mediated signaling pathway; and receptor signaling pathway via JAK-STAT. Predicted to be located in cytosol; nucleus; and plasma membrane. Human ortholog(s) of this gene implicated in Zika fever; immunodeficiency 44; and neutropenia. Orthologous to human STAT2 (signal transducer and activator of transcription 2). [provided by Alliance of Genome Resources, Apr 2022]
