Summary: Enables DNA binding activity and protein heterodimerization activity. Acts upstream of or within embryonic pattern specification; lung development; and negative regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including alimentary system; future brain; genitourinary system; limb; and skeleton. Orthologous to human SIM2 (SIM bHLH transcription factor 2).

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.
