Arnt2 - aryl hydrocarbon receptor nuclear translocator 2

Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; aryl hydrocarbon receptor binding activity; and protein heterodimerization activity. Involved in central nervous system development and positive regulation of transcription, DNA-templated. Acts upstream of or within in utero embryonic development and positive regulation of transcription by RNA polymerase II. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human ARNT2 (aryl hydrocarbon receptor nuclear translocator 2). [provided by Alliance of Genome Resources, Apr 2022]
