Summary: Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; LIM domain binding activity; and transcription cis-regulatory region binding activity. Involved in several processes, including negative regulation of cell population proliferation; positive regulation of cell communication; and positive regulation of macromolecule metabolic process. Located in cytoplasm and nucleus. Part of transcription regulator complex. Biomarker of type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in atrial fibrillation; congenital heart disease (multiple); diabetes mellitus (multiple); dilated cardiomyopathy; and myocardial infarction. Orthologous to human ISL1 (ISL LIM homeobox 1). [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.
