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 several processes, including abducens nerve formation; cornified envelope assembly; and negative regulation of osteoclast differentiation. Acts upstream of or within several processes, including T cell differentiation in thymus; brain development; and thymus development. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb; and sensory organ. Used to study Duane retraction syndrome and multicentric carpotarsal osteolysis syndrome. Human ortholog(s) of this gene implicated in Duane retraction syndrome and multicentric carpotarsal osteolysis syndrome. Orthologous to human MAFB (MAF bZIP transcription factor B).

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.
