Summary: 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). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (b) lacks an alternate exon that results in a frameshift in the 3' coding region, compared to variant a. The encoded isoform (PBX3b) has a distinct C-terminus and is shorter than isoform PBX3a.
