Automated description from the Alliance of Genome Resources (Release 7.0.0)
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 adult locomotory behavior; nervous system development; and regulation of respiratory gaseous exchange by nervous system process. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; branchial arch; genitourinary system; nervous system; and sensory organ. Orthologous to human PBX3 (PBX homeobox 3).
