Enables CCR5 chemokine receptor binding activity; protein phosphatase 2A binding activity; and sequence-specific DNA binding activity. Involved in several processes, including positive regulation of nitric-oxide synthase biosynthetic process; positive regulation of smooth muscle cell proliferation; and receptor signaling pathway via JAK-STAT. Acts upstream of or within cellular response to cytokine stimulus and cellular response to organic cyclic compound. Located in several cellular components, including axon; dendrite; and nucleus. Used to study pulmonary fibrosis. Human ortholog(s) of this gene implicated in breast carcinoma; immunodeficiency 31A; immunodeficiency 31B; immunodeficiency 31C; and prostate adenocarcinoma. Orthologous to human STAT1 (signal transducer and activator of transcription 1). [provided by Alliance of Genome Resources, Apr 2022]
