Summary: Enables DNA-binding transcription factor activity, RNA polymerase II-specific and transcription cis-regulatory region binding activity. Involved in positive regulation of DNA-templated transcription. Acts upstream of or within several processes, including circulatory system development; hair follicle development; and stem cell fate specification. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; integumental system; and urinary system. Human ortholog(s) of this gene implicated in hypotrichosis-lymphedema-telangiectasia syndrome and hypotrichosis-lymphedema-telangiectasia-renal defect syndrome. Orthologous to human SOX18 (SRY-box transcription factor 18). [provided by Alliance of Genome Resources, Jun 2025]

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.
