Official Full Name: iroquois homeobox 2provided by RGD
Primary source: RGD:1309834
See related: EnsemblRapid:ENSRNOG00000012742 AllianceGenome:RGD:1309834
Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Summary: Predicted to enable DNA-binding transcription repressor 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 negative regulation of transcription by RNA polymerase II; neuron differentiation; and proximal/distal pattern formation involved in nephron development. Predicted to be active in nucleus. Orthologous to human IRX2 (iroquois homeobox 2). [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.
