Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including cell surface receptor signaling pathway; positive regulation of endothelial cell differentiation; and positive regulation of mesoderm development. Predicted to be active in nucleus. Is expressed in several structures, including genitourinary system and hemolymphoid system. Orthologous to human ETV2 (ETS variant transcription factor 2).
