Also known as: BETA4; Beta3b; Bhlhb4; A930001L02Rik
Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within eye morphogenesis; negative regulation of retinal cell programmed cell death; and positive regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. Is expressed in several structures, including brain; branchial arch; limb; maxillary process; and urinary system. Orthologous to human BHLHE23 (basic helix-loop-helix family member e23). [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.
