Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including insulin secretion; nitric oxide mediated signal transduction; and response to glucose. Predicted to act upstream of or within positive regulation of transcription by RNA polymerase II. Located in nucleus. Biomarker of diabetes mellitus. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human MAFA (MAF bZIP transcription factor A). [provided by Alliance of Genome Resources, Apr 2022]

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.
